having big problems

do you want more control or more speed cause it also depends on the sponge

i can do good smashes and alittlte bit of heavy topspin just dont know what rubber should i use

do you brush or hit into the sponge?

actually a hard sponge has good control, contrary to what jake had said.
although theres a gazillion rubbers out there so theres always gonna be irony.

soft spong is hard to control, espcially during the short game, too bouncy.
eg. i play donic f1 on my fh for pushing, good lord it pops up!

tacky rubber might help you, but u really have to generate your own pace

thats cause theres a set of different techinques using different rubber.

euro, medium soft grippy rubbers

vs

tacky hard chinese.

Horses for courses. If you don't like tacky rubbers then use non-tacky. If you're missing easy putaways then you have bigger problems ahead of you than equipment.

so what should i do

i m using bryce speed on fh and i must my forehand has improved very much since i have been using it is the backhand i m worried about i only bought tg3 because it was cheap so iwant to chage asap so i once i used jp gold i liked it then so can u guys me any taughts about it or shuld i spend little bit more money and buy tenergy.
