why T05 forehand and T64 backhand?

Well I use T05 on BH, no problem for me. Haven't tried T64 though, waiting for spin art.

There are much more PRO players using T05 both sides than players using T05 f/h, T64 b/h.

It depends on the blade.
What blade do you use ?

I've played Innerforce ZLC with T05 two days ago. Feeling WASN'T bad.
I used only for 5 minutes, so I cannot tell you if T64 would be better.
Generally speaking, I don't think that ZLC "needs" a specific Tenergy.
Just buy any of the two and don't worry.

I guess a lot of players prefer that setup for the same reasons many players prefer chinese rubbers for fh, and japanese rubbers for bh.

The T64 is bouncier, and produces more power on blocks and short bh-loops. (shorter stroke than the fh)

The T05 is spinnier, and produces more power on the longer fh-strokes.

Generally, FH technique for most players is better than their BH technique. T-64 is a bit more forgiving and therefore plays better on BH. But that's only when we are talking about non-pro players. There are plenty of examples when pros are playing with T-05 on both sides, T-64 on both sides, T-64 on FH etc.

The weight difference between T05 and T64 is minimal. For a cut rubber the difference is 3-4 g. tops! There is only 1 g. difference between my lightest T64 and my heaviest T05.

You must be really sensitive to weight!

I have been playing 05 FH and 64 BH for a week or two now. My BH is spinier than my FH and I open more rallies with BH, but it is hard to get the proper angle for counterlooping with BH. I would really like to try T64 on both sides of my MJ.

It has everything to do with the ball throw and the speed.  For most players their backhand is weaker (physical strength, not necessarily skill) and the forehand is therefore stronger.  This makes perfect sense because the forehand is a much longer stroke resulting in greater potential for higher racket speeds.  That is the "speed perspective" way of reasoning for using T64 on the backhand, due to it being faster than T05. 

The more obvious reason though has to do with the difference in throw angles.  Due to feeling awkward as well as your body getting in the way of creating a higher (in relation to the table surface) and longer back swing, it is much harder to create a horizontal stroke from the backhand (racket face parallel with the table surface).  Having a rubber with a low throw greatly assists with this problem, such as T64.

Of course this is all relative though.  Even though it has a low throw compared to T05, T64 has a noticeably higher throw compared to other tensioned rubbers such as Bryce Speed or Express I.

This will most likely be my very set up once I receive my SK7.

I tried T64 on my FH rather than T05. I love it. the speed is faster than T05 and easier to loop.(softer). the arc is flat..the sound is great...I would like to try T64 on both sides as well....

I meant to say 05 BH 64 FH, but yeah I still wanna get 64 both sides
