Chinese = Tacky (flypaper based)
Euro/Jap = Grippy (friction based)

Sponges aside, which top sheet is capable of generating more spin?

Recently, I've got several DHS H3 topsheets that are extremely tacky (hold the ball over 20 s.) but are very low-productive in the spin department. So I presume the belief tacky rubbers produce more spin is an urban myth.

Just considering spin alone, tacky top sheets can produce more spin as it allows you to finely graze the ball.

Simple Analysis : How many of the top 25 ranked players in the world use a tacky topsheet on their 4H ? The 4H is considered dominate in their style. A tacky top sheet, with the proper technique, allows longer dwell time of the ball on the rubber, therefore should produce more spin !

Tacky (Chinese) wins easily !

Reflection at the amateur level: The majority of non Chinese players do not use a tacky top sheet.

The number is probably less than 50% and believe it or not, there are Chinese players who do not use tacky topsheets as well.  Just about every non-Chinese player in the top 25 uses a non-tacky topsheet.

It depends on
(1) the stroke you play - ie it's different for a push compared to a loop
(2) the way you brush the ball

I get loads more spin on my serves with a very tacky rubber, but get more spin on loops when it's only mildly tacky.

Tackiness is primarily for controlled low gear, not for spin. Pimple structure and elasticity of rubber handle the spin. You'd better believe it!  Lets the war begin! :)

So why not list the 13-15?  Just playing semantic games?  If we assume the 11 Chinese and maybe Gao Ning because he is originally Chinese, we get 12.  Who are the others?  And the question is why aren't the non-Chinese doing it?

Not sure if this is true, but the majority of the Chinese use tacky top sheet and they are the best. But, who here thinks they are the best due to their tacky topsheets?

Another thing to consider here is, ´for what shot is the topsheet the most important? According to me, it's brush strokes where the sponge don't come in to play much, so, more or less the touch shots, such as serve and serve return. And, most top players of today seem to prefer to return serves with their bh. How many players use tacky rubbers on their bh?

In the end, its a matter of personal preferences. Like Haggisv said earlier, Ive found that tacky rubbers generate more spin on serves (not significantly, in my case) while I seem to get more spin from grippy rubbers in other parts of the game.

From a piratical sense, I'm beginning to find tacky topsheets overrated a little.

I've owned several tacky rubbers. I clean them after playing. I use rubber protectors and I still feel like in relatively short time, they morph into more grippy vs tacky. Any pick up the ball off the table trick you can do fresh out of the packet is a far cry from what you'll get that rubber to do a month down the road... At least it has been for me.

Now all I want out of my topsheet is for it to have high friction. Is it hard to slide the ball across it? Do I have to apply a lot of force to get it to do that?

As long as I have that, I'm happy with my topsheet... Beginning to see the value in putting your money into a quality sponge.

Tacky top sheets are great if you can brush a lot because the ball will not slip of the paddle but the same force that hold the ball must also be broken so that is a net zero when it comes to speed.
It is a pain to keep tacky top sheets clean.

It is the top sheet stretching and snapping back that causes extra spin in excess of what would be generated by friction alone. How many times do I have to say this?

depends on the player, and the player's technique (skill level)

what i have found is at lower speeds (on service game, table game) the tackier rubbers produce more spin, however at high speed (counterlooping/driving) tenergy produce immense spin (provided you are swinging full or at a high rate of speed), yet personally i find that my service game with tenergy is not nearly as spinny or dynamic (but, that's me)

but, it's also technique, because i have played/practice with players who use hurricane and tenergy both, and their balls come over with barely any spin, kinda like hitting a change-up on every ball.  so it's not a 100% answer that a certain type of rubber will automatically produce more spin

Tack is there for control mostly. Apart from serves and top gear, grippy rubbers are spinner in my opinion.

Honestly though, the topsheets that the CNT are using aren't even that tacky at all. The tackier the topsheet the more of a limit on speed you will have.

Like I said, it is more a matter of how much the ball can stretch the top sheet across the face of the paddle and then how fast it snaps back to the original state.

Without the stretching and snapping back action all the top sheets would produce the same spin because the surface of the ball would be moving at the tangential speed of the paddle and that is it.

If the tackiness is high I wouldn't be surprised if the tacky force reduced speed and or spin.

it is not a matter of tackiness vs grippiness.  it's how tacky or how grippy the top sheet is.  a slightly tacky rubber is not as spinny as a very grippy rubber and vice versa.  it's how much friction the top sheet can produce.  different rubbers, whether tacky or grippy, have various degrees of friction.

I thought we settled this a long time ago (hint: tangential elasticity).

And watch Wang Liqin bounce the ball on his "tacky" topsheet before serving. Super tacky? Uh, no.

I used to play with DHS PF4. I can't imagine anything stickier than that. I could hold a ball upside down for about . . . well, the ball never came off! Many players used it for chopping. Is it fair to say that was spinnier than most friction-based rubbers?

The most spinny is chinese players spin....
And they are using tacky rubbers on their FH
It means that tacky rubber for best spin...

I rest my case (as stated in post №2): Tackiness alone does not increase the spin. There should be something else to produce greater spin, e.g., grippiness.

It's also a question of stroke.

With tacky topsheet you need to play with all your arm to produce high spin.
With grippy topsheet, with only first part of your arm you produce spin.

This 20 years old study indicates that sticky rubbers produce both less speed and less spin:

http://www.ittf.com/ittf_science/SSCenter/docs/199408014%20-%20%20Tiefenbacher%20-%20Impact.pdf

Unfortunately we cannot be sure if they took into account the effect of different sponges during these experiments (ideally they should attach different topsheets to the same type of sponge to be more conclusive)

Tack and frictional force (grip) is just not the same thing.
Tack is related to an ecqual opposing force perpendicular from a surface as from ballweight.
Hence the tack is also perpendicular to the rubbersurface as a force (not just a force component).
Grip,frictional force runs parallel to the contactsurface (no matter how soft the sponge).
No less then ninety degree difference between tack and grip.

Two rubbers can have same tack and be completely different for frictional force.
A test example would be to pour some honey on a rubber and spread it evenly as a thin layer. The tack on a ball will be quite good but grip will for sure be  lousy.

So called grippy versus tacky, european or japanese versus chinees only mixes this up and confuses.

Another enlightening testexample can be to cut a broken ball in parts with much less weight then a ball.  Pressed firmly to a Tenergy rubber it has good chance Tenergy can lift this for hours if the piece of celluloid is light enough.  So obviously Tenergy is tacky also (allbeit less then Hurricanes).

Wether the maximum lifted weight is more or less then the full weight of a ball is arbitrary for making such a distinction between tacky and non tacky.
