I played with G-1 on my backhand for 3 years. It is fine. Fastarc series has the least catapult effect out of the ESN. G-1 is fast and it is very direct. Wherever you want the ball to go, it will go there. I personally would start with C-1 and get used to the Fastarc series before upgrading to G-1. Nobody reallly uses P-1 or S-1. You can strike those two out of the equations.What do you think about Nitttaku Fastark G-1?
G-1 and C-1 I believe are two of the best selling rubbers on TT11 and in Japan.
