I'm an advanced player who up until a shoulder injury have been playing wth a Tour 10 MP weighted at 345g. The injury is now almost completely healed and at age 38 am looking towards the future where I can play for a long time without another breakdown. I've been thinking about the Catapult racquets ( Cat 4,6,7,10, V1, & V10 VE) and was wondering what people thought about them. Do they make less work for a shoulder and what experiences and comparisons can you make between them. While the Cat 10 seems the softest I'm not sure weather you lose out on power compared to the other Cat's and have they been discontinued due to lack of interest or just to make way for the V10 VE. The Cat 4 and 7 are longer racquets, are they a liability or asset to a player.
