Like this rubber with thin sponge on my Donic Epox TopSpeed. With the thin sponge it was very easily controlled and was great for low serves fast and slow. Not very bouncy, but the blade made up for that. Great on fh. Felt very clean and crisp and predictable on topspin smashes. Feels really lightweight.
Without speed glue it is less effective, for speed. It can be played on any speed racket. You can get very high spin on serves. It is usually offered in several thicknesses. Thick for offense, thin for defense, or medium for allround. If you read spin well, you will have very good control.
not the best rubber ever. very spinny, very very soft. not a lot of control or speed. I used it early in my development and I feel like it set me back quite a bit as a young player. with (much) more experience nowadays, I still don't really like it all that much. it was kind of a big deal in the late 90s, and probably was a monster with glue in a ~2.0 sponge, but nowadays there are better options.
