Hi, my first post here. I've been playing been tennis for a few years now and I've been playing hand me down racquets until now as I'm getting more serious about it. I reviewed the characteristics of the racquets and I still don't understand the difference between these 2 concepts. If the weight of the racquet is 11 oz. and the swing weight is say, under 300, would it be the same as a racquet that is 9 oz. in weight and a swing weight of 330? What is the difference in terms of feel? Which one produce more control and which one more power?
