<< TOUR VERSION/EDITION - TOUR VERSION/EDITION - TOUR VERSION/EDITION >> AS OF 7/30/08 WE ONLY HAVE THE 4-5/8 GRIP,, BUT WE CAN RESIZE THE HANDLES USING HEAD ORIGINAL PALLETS SO THAT WE MAKE 1/4, 3/8 OR 1/2 TO FACTORY ORIGINAL SPECS.... THE COST TO DO SO IS CONSIDERABLY MORE....SORRY Head Ti.Fire Comfort Zone - Tour Version tour version is about 1 oz heavier than than the non-tour version. also the racket is approx 1/4" to 1/2" longer... the racket is also more head light so it is more manuverable.. because its balance is lighter it does not feel heavier, but it makes for more solid hitting...
