So far in comparing it to my Volkl Quantum 8, the Surge X seems to have more power and more control and is quick for volleys and pretty solid from the baseline too. My timing is a little off so far from it being headlight and having a faster swing despite it being a half ounce heavier than the Volkl Q8. I may still need a heavier racquet in my goal to move up, but I think this racquet is going to help me to continue to improve. It is only 11 ounces. Anyone else use the Surge X? or the Volkl Tour 8 which was my other option but wasn't in stock at the time.
