i have tried most of the club sets available, master tier and pro tier, and in my honest opinion the ping pro raptures are the best.. i thought with the added precision the master i15 and the other set would be better, but any slight miss of the meter line and ur in big trouble.... there is no consistency with the master clubs... the fast meter swing is hard enough, if u try to composite and hit it not exactly on the line it just goes wild.. the control is not that good, and i personally think the master clubs are a waste of money... stick with your pro irons, just upgrade your driver for that extra yardage from the tee.. i even brought the new master putter.. was horrendous.. have gone back to the 750 credit putter.... my friend made master the same time as me and stuck 2 his pro+clubs, just upgraded his driver, he plays like a master, while iam more like a hacker.... even when u hit it perfect on the meter line it seems to go of target... i wish i could downgrade back to raptures, but this new level system has stopped me doin that... its stupid.. do not upgrade to master irons or the master putter..
