I have played a lot of tacky rubbers before (Bloom Spin/ Power, Origin, H3/Neo, G666, TGII) and I think its helpful to give them a little massage to break in. Just press the rubber with your fingers down firmly over and over again for a few minutes (with protection sheet applied)- this has the same effect like hours of playing.
Now I play Joola Golden Tango PS where the break in process isnt that noticable. I can recommend this rubber as a good upgrade with higher arc for more safety over the net. With discount it is like 35€ so not as expensive as other hybrid rubbers.
I had two sheets which were very tacky now two sheets only slightly tacky (i like stronger tackyness better).
Ive read some good reviews to the new STN and the Jupiter 3 and i am curious about the arc.
Is it comparable with hybrid rubbers?
Maybe I would try one of those as they seem to be more tacky than the Joola GT PS.
I recommend trying Jupiter 3. It is incredibly cheap and this test will be almost free for you. In principle, this could have already ended, but I will continue.
Jupiter has good grip and control but not high speed. The stickiness is not great, the angle is moderately low, the ball flies straight with almost no arc and is very unpleasant for the opponent. Without a booster, in my opinion, the rubber does not reveal all the possibilities, two layers of Seamun are needed with a break of three days, so I cannot recommend it to all fans. Regarding Jupiter 2, the choice of sponge hardness has been expanded - these are 37, 38, 39, 40. Hardness 39 is optimal for me.
