We all know players walk on to court with 6-10 freshly strung racquets, but are they all brand new. If so how many racquests are used per tournament and per year for that matter. Are 12 racquets used for a single open from start to finish. Or is it Round 1=10 / Round 2=10, 3=10, qf=10, sf=10 and finals=10, so thereby 60 per tournament. Any info? And so then basically what would be the yearly racquet consumption figure per pro player. 50, 100 or even 3000? Fellow guessers need not guess! Please ppl who know the facts or have a very good idea please reply!
