I actually played with G-1, C-1 and now P-1 in the last 2 months
I played last full season with G-1 on backhand and I had a little bit of a love-hate relationship. On the one hand I liked the spin, but I felt it was lacking some control in the faster open rallies.
After season was over I decided to try C-1. It was quite difficult to transition. C-1 was quite a bit slower and I really had to adjust my technique on topspin strokes because I wasn’t used to playing with a softer rubber. After 4 weeks of using it I got used to it more. I was making less mistakes when under pressure, but it was also harder for me to put pressure on the opponent. I could either play a slow topspin, or a fast punch shot. I couldn’t get the technique right to hit hard topspins which felt like a playing with a handicap for me. Open-up against backspin was easy and smooth. However there was a noticeable lack of spin compared to the G-1.
Eventually after a little over a month of C-1 I couldn’t help myself to try P-1. Since the sponge of P-1 is the same hardness as the G-1, but it has a softer topsheet. And I have to say from the moment I tried P-1 it instantly felt better then C-1 for me. I could finally hit hard topspins again and it had more spin then C-1. However, I have also been using it for about 3 weeks and I find there is 1 downside compared to both G-1 and C-1 and that is open-ups against backspin. I have turned my racket around a few times lately, since I still use G-1 on forehand. And I have to say G-1 feels more consistent. With P-1 it feels like you have to be more precise to consistently hit your shots. G-1 just feels better allround.
So for me after trying them all I will go back to G-1 eventually. If you want something different then G-1 I would suggest C-1. It gonna be slower and not a spinny as G-1. But its more foregiving if your backhand isn’t as good. The P-1 is not a rubber I would suggest to anyone (at least not over G-1), for me it just feels like a worse version of G-1.
