Tau2, as mocker88 said is definitely more bouncy, the sheets I have tried have retained tack very well.
If you don’t want to boost, and still want a tacky top sheet then the best options are the hybrid type rubbers.
There are a lot of hybrid options these days, it a case of trying to find one that sits in the correct position on the scale between tacky or grippy top sheet and ‘dead’ or bouncy sponge that you are happy with.
for example D09C is, for me, a rubber that has minimal tackiness, Donic Bluegrip C1 is similar, they both have very bouncy sponges. These are closest to a rubber such as T05 or Bluestorm S1 and furthest away from H3.
Victas TDE, is much closer to H3 and further away from T05 etc
H8-80 is closer to H3, and perhaps Tau 2 sits around halfway between H3 and T05 (especially after it has ‘matured’)
A week or so ago I put a new sheet of H8-80 (38 degree) and a sheet of Rakza Z EH on a blade, I have only done some serve practice with them.
Both were equally tacky, holding the ball for 3 seconds+, for serving both were very similar in feel speed and spin, couldn’t notice any difference!! But I know the difference will become more noticeable when I start playing topspin and loops etc I’m expecting the Rakza Z EH to be more towards the T05 end than the H8-80. When I give them a run out I’ll know for definite!!!!
