It's not speed I'm looking for, it's more of that feeling that carbon gives you that you can spin with minimal effort. Essentially, carbon does the hard work for you. On the contrary, whenever I go from my fb2x to my infinity I always appreciated the increased dwell and how that could give massive spin potential as well as safety.
What 7 ply's do you recommend? I was going to buy a used nit acoustic- but I'd be happy to see what you recommend. (DHS PG.9 looks attractive to me- or maybe fang bo all wood)
PG9 is a good blade. Fairly thick with a strong catapult effect, very strong topspin with Chinese rubber. Fast but not as hard as most carbon blades.
Never tried PG13 but it does have a unique construction similar to my defensive blade but thin carbon middle instead of wood. Did use PG12 for a while. I didn't like it, far more stiff and hard than PG9.
