I have used tight-patterned Heads (Ti.Radical OS and Ti.Classic MP) and found that for some strange reason, I'm able to get more movement (spin/break) when using those rackets than when using the more open-patterned Wilsons (HPS7.1 and HPS Surge). I really see more jump/movement on my serves (slice and kick). I'm not really doing anything different (at least I don't think so). Am I alone in this or have others that have used rackets with tighter string patterns noticed similar behavior? Does Head seem to know something that the other manufacturers don't? It almost seems as if by comparison to Prince, Wilson, Babolat and Dunlop, their inventory seems to favor tighter string patterns.
