I don't understand how some rackets are described as lacking power. I am only an intermediate and I find plenty of controlled power with my Bio 300. The Bio 300 allows me to ping the ball from corner to corner with relative ease, I would have expected this new version to be broadly the same as the previous but with a different PJ.
