I've been using C55 on my FH for most of a year on my forehand, but could not help but feel that C55 was a bit too hard and thus somewhat unforgiving, especially when I'm under pressure in a real competitive match. Hence the dalliance with Dignics 09c, etc.
So I was very excited to test C52.5 on my forehand and, after a couple practice sessions, it seems to be a perfect forehand rubber for me, very promising. Same mildly tacky and very grippy topsheet as on C55, but the slightly softer sponge makes the rubber more dynamic and safer to play and therefore I am no longer hesitant to hit the ball hard wheh under pressure. Definitely prefer this rubber over Dignics 09C.
Ofc, the real test shall take place at the Hereford tournament next weekend 🤣
