I played a couple of 8.5 combo league matches last season and one guy on the other team used 3-4 different rackets all the time. He would serve with one racket, return with another racket, volleys (when his partner is serving) with another racket. Surprisingly, he actually played well with all these different rackets without any adjustment time and won matches. I am talking about totally different rackets (Head LM Prestige Midsize, Wilson PS 6.1 Classic, Babolat Pure Drive, Wilson nCode 90). Is he insane or just talented?
