I've played the Catapult 4 and did not like the catapult technology at all! I currently play with the Quantum Tour 8 and enjoy it very much, but wish the racquet supplied a little more power. Everything that I've read points to the V1, while I plan on demoing both versions, I'd like to hear what others think and yes I've read all of the posts as well as the reviews. Most seem to lean towards the OS, but it sounds too good to be true! Larger sweetspot, additional pop, increased spin, and great control! What's your experience / opinion?
