Project X's Rifled shafts are really nice... I would recommend the Rifled Spinner shafts for your PW-SW-LW if you have a decent club and they are worth the $... I use a Golden Bear SW cuz I tend to hate that club the most and use it to practice my Club Throw (
Throwing Your Club by Top 100 Teacher Charlie King | Homepage | Golf.com) LoL. Enjoy your new shafts.
