As the serial number regards, at the side of the blade, maybe DHS has new numeral system for the production serial. ( they used to print the production date with numbers, and now they have changed it into alphabetical system...)

What can I say... 

Wish you from my heart to be genuine!!!

The finish of DHS baldes certainly is not the best. Not even close to Nittaku or BTY products.

My friend buy 2 rubber (H3BlueNational) from prott. But he to return it because it see not similar.

I'm understand @MLfan, "it's a copy...bad". Yes! it's true.

No holographic sticker as you can see. Note the head size is smaller too. 156.5 x 150 for me.

For security purposes I scratched out the identification number to prevent it from being used by fake manufacturers.

If you want I can go to my club tomorrow and ask the equipment dealer if I can take pics of the blade (provided that it's in stock).

Do you have picture serial on blade?

The old version had a slimmer center to its flare shape.  The head looked outsized and large. 

Sorry, I wasn't thinking straight when I commented. The blade's a real HL5 blade, but it's the commercial blade, not custom-made. 

I have used a TB ALC from someone for like a few minutes. First impressions is it's a very stable blade but has less power than my Viscaria. Other than that, the rest is just from watching other people play with them. HL5 is definitely faster. When I twiddle my racket around to use t05 on my FH, It's slightly faster than my viscaria with t05 on the FH. Overall, I'm leaning towards HL5 being the better blade for now compared to my Viscaria. But honestly, it's very close. Viscaria like I said is better for BH and I find that the control for the HL5 is much better after playing with it for a few months.

The BH is quite different from any other blade I've used (well, it's kinda similar to the DHS-WL that I've been using). You gotta put a little bit of power into the blade if you want your ball to travel lightly across. Passive strokes are better for touch play due to the dullness of the blade. I've read some people using EL-P with the blade. May I ask which parts aren't playing that good? BH loops? BH flicks? BH pushes? BH touch play? BH drives?

I've used Rakza 7 and Tenergy 05 on my BH.

Rakza 7 - BH flicks are really good. You can feel the ball grip the ball and you definitely can tell where it will go. Pushes and touch shots were a bit long and high with the rubber. BH drives are good. BH loops took a while to adjust, but after adjusting with a more closed angle, it's easy to land the loops. BH flat shots weren't that well controlled. I changed to t05 because I prioritized my touch shots and pushes a lot and they were causing me to lose a lot of my points.

Tenergy 05 - BH flicks are alright, but not as good as Rakza 7. When I don't get sponge penetration, I honestly don't know where I contact the ball, so there's a bit of anticipation involved if I want to get the shot I want. The rubber doesn't grip the plastic ball as well as I would like. When I tried on celluloid balls, it's easy, but people don't play with those anymore so it's a no-no. Touch play and pushes are much easier. Ball can be kept low and hard to attack but if you make a mistake in reading the spin, it will go high and result in an easy victory for your opponent. BH loops I find I have less control when I'm just right at the table. It takes a lot of focus to make the loop land short or just barely on the table, especially since I don't get much sponge penetration and the fact that I'm literally just brushing the ball and couldn't feel the grip. Mid distance it is so much easier to control and do BH loops and get them in. BH drives are very good. But flat shots are horrible when paired with the HL5 compared to my Viscaria. It's taken me a while to get the control down. I'm going to try out Andro Rasant Grip and Rakza X since they are marketed for control and they grip the ball. I've had a lot of experience with Andro Rasant Grip and I have to say I love it more than tenergy. Not sure how well it will play since I'll get the rubbers sometime next week.

On Chinese forums, some BH rubber suggestions for the HL5 are:
H3 Neo Provincial 37 degrees 2.1 (don't think most people can obtain this and be confident they have the real thing)
Tenergy 05 (People say it can be difficult to control if you don't engage the sponge LOL)
Tenergy 05-Fx (Very stable according to a lot of players)
Tenergy 64 (Ma long loves doing punch/flat shots close to the table (technically there's a bit of spin as well) and loops with his BH when he's mid distance. Used in his 2013-2014 games. The loops might be a bit weaker now because of the plastic ball though.)
Andro Rasant Grip
Andro Rasant Powergrip
Xiom Omega IV (don't know which version they recommend, asia, europe, etc)

Xiom Omega V (I see this a lot as well, but I don't know which version to use)
Donic Bluefire M2
Donic Acuda S2 (I've seen this one mentioned in a lot of message boards, so it might be something to worth trying)
Palio AK47 - yellow packaging (cheap and stable - don't know what yellow packaging they are referring to though, might be something you can only get in Asia. Found the link: http://www.dpin100.com/goods-5187.html)
Tibhar Evolution EL-P (one person said it was stable and had a good time brushing the ball with it)

Tibhar Evolution MX-S (recommended by one of the coaches/teachers on the forums who's pretty popular and also said T05-Fx is the best for new HL5)
Rakza X (Based on what a few China National Team members have recently switched to like Fang Bo, Zhou Yu, and Yan An. Fang Bo had really bad BH when I checked his games of when he started using W968 which is like the better version of HL5 and it became better in the Chinese Super League when used Rakza X. Zhou Yu I believe used Tenergy 05 previously and was dominating in mid distance loops, but his close to the table loops and flicks had lower accuracy.)

I also recommend getting some coaching. It took me a while to get my BH stabilized on the HL5. It used to be like 80-90% accuracy with my Viscaria and when I changed to the HL5, it was like 30% accuracy. Now it's around 60-70%. Still a lot to work on. I say don't give up on the EL-P yet and try tweaking your angles a bit.

I also tried the W968 replica's sold by TTNPP. Perhaps I didn't give them much "break in time" but it vibrated so much it disgusted me. Ended up chucking them away.

Right now I'm using 2 "authentic W968", trivial and questionable, but I spent too much to throw them away hahaha. Anyways, initially, it reminded me of the W968 replicas (a lot of vibration). But after the break in period (perhaps due to humidity, moisture absorption, constant gluing... etc. ~ 1-2 weeks) the blade feels better (softer) than the new commercial HL5 (can be subjective, relative and bias of me). Compared to the commercial HL5, the W968 provides higher arc.

My fall back weapon is always the viscaria (I have 2, the control is just unsurpassed in my opinion). This is also subjective, but viscaria plateaus on power. HL5/W968 on the other hand are pure attacking beasts.

I had Tenergy 05 on my backhand and it is bouncy when you start engaging the sponge. I twiddle it on my forehand when I'm making powerful smashes because Hurricane is not good for smashing. The forehand loops are devastating and pairs quite well with the HL5. Close to the net shots were a bit hard to control especially when the ball clips the net and gets some extra spin. Ball will always fly out even when I close my angle when I try to hit it flat. It's a bit more accurate when I add spin by using a flick but not as accurate as I would like. Touchplay is really good, especially for serve receives but sometimes like you say, it can be hard to feel the ball. In general I like t05 for the FH because of the loops and touchplay in keeping the ball low but BH is quite a nightmare. Only thing good about the BH is the touch play shots and BH flicks (although flicks can be challenging as well since I don't feel the grip that well on the plastic ball). Opening BH loop is pretty inconsistent compared to lots of rubbers I used. And the feel isn't as prominent as I would like as you have mentioned. I've recently just changed my BH to andro rasant grip which is slightly heavier but this is increased feel. I had the rubber cut 1-2 mm wider than the head size and the weight changed from 183g to 187g. Touchplay is really good, even better than tenergy 05 in my opinion. The grip on the ball is incredible, my opening BH flicks are nice and low and my opening BH loop percentage has went up considerably (I'd say from like 20-30% to like 70-80% which was what it was when I was playing with my other rackets). Only downside is after the first loop I gotta remember to flick or add spin to the ball a bit when it comes back otherwise it hits the top of the net. Still working on this with my coach but my coach says it's a big improvement. Still in the honeymoon phase, so I got to play a bit more to see if I really like it, but so far so good. The control is very good. Only cons I would say is the heavy weight, the spin sensitivity (people have mentioned this, but I don't see it as a problem), and the low arc (pairs well with the HL5 which has the catapult effect, so it evens out).

Tenergy 80, I have it on my viscaria as a BH but I have used it on the FH when I've twiddled the racket. T80 in my opinion has a lot of control, way better than T05. Spin is slightly weaker so if your FH loop is very spin dominant, you might not have much power. I like the T80 more for flat hitting and it has just enough grip to get my BH flicks done but not as much as T05. Pushes and touchplay are good as well.
