They may seem like a very stupid question to be asking but, what is the difference between topspin and control. here is a statement I found online... An open string pattern has an increased gap between strings for better grip when applying spin on the ball. A dense string pattern offers more control of the ball, but requires more power for applying spin. So, I read it a few times and I'm still lost. a dense string pattern is for more control but it requires more power for spin???? what does this mean? so control versus topspin, which is more important? I guess I understand spin, the more spin off the racket the slower the ball travels but you keep it in play. but the control aspect is what's throwing me off. please help me!
