Please recommend me some rubbers that are slightly slower than sriver. I went to buy rozena but it was way to fast for me. And now I have a bad habit of kinda poking the ball.
Mmm. When I started playing Sriver was considered a fast rubber, and the Mark V I played with crazy fast; but these days it's quite slow in comparision to most. Rozena's fast, but not insanely fast; I find it to be quite controllably so, with no impediment to making full strokes, but your mileage obviously varies. Sriver is quite a few steps down, are you really sure you want something slower than Sriver?
That would probably take you into the realm of Chinese tacky rubbers, or a hybrid rubber. DHS Hurricane 3 (Neo, I'd guess) and Hurricane 8 are slower than Sriver (though not by all that much) and way spinnier.
Stiga Genesis and Genesis II are not all that fast and very spinny, and are somewhat Chinese-ish in play.
In Euro-style rubbers, something slower yet spinnier than Sriver is uncommon. I don't think Sriver EL and Sriver FX are not much slower (if at all) and not spinnier (if at all) than Sriver (L, I'm assuming; Sriver S doesn't exist anymore, AFAIK). I've become somewhat of a GEWO rubber fanboy, being positively surprised by much of what I've come across, including a few (relatively) slow but spinny ones: Nanoflex FT 40, and Neoflexx eFT in several sponge hardnesses. And there's Xiom Vega Intro.
