I think paintjob upgrades will be the new model for racquet companies-babolat has been doing it for years, surprising that it's taken other companies as long to get on board. Think about it-before cortex, babolat basically had three real racquets: pures storm, drive, and control, with no new technologies for years, just paintjob upgrade and maybe an additional version (98 and 100" versions of same racquet, pure drive oversize) . They did it again with the Apdc and now with the pure storm gt. Has to be cheaper to just change paint and add the occasional "lite" or "team" version than to spend $ on R&D to find the next "lightest and most stable compound" that doesn't really affect the way the racquet plays. And honestly, we're dumb enough to buy the new paintjob over the old one even though the same stick is underneath. And when they do put out a new technology, we'll buy that too.
