It’s interesting how much companies invest in R&D. Look at Wilson – they probably introduced that nJunk because it’s cheaper to produce – 2 times cheaper, 2 times more advertising = 22 times more money. Wilson has not invented something useful since the PWS. Their new Racquets are “designed”. What about Head? Their Total Sweet spot construction is theoretically impossible. Who are they kidding? Or Prince – nothing since the POG. It seams that only Babolat is trying to invent something. No, seriously, I’ve heard that their new Aero Control racquet is good.
