I have been playing quite a while but it is until recently that i decide to really get into the technicals of racquets. just a few stringing terms i dont get while i am reading some of the specs: - open string pattern (opposed to closed???): what is it ? how does it affect play? - shared holes: how does this affect play? - string pattern: i have seen specs of same size racquet head (eg N6.1-95)but different string pattern, how does that affect play? and in general what will be the difference in play for say if i have 16*18 vs 18*20 - main skip: 7H, 9H .... etc .. two piece : what does this all mean? i hear always talk abt string patterns and i always thought it was correlated with racquet size .. ie bigger head = more mains & crosses.. but anyway ur help is much appreciated.
