hi mike
i contacted ping about your clubs and the say it the weight behind the blue ping name on back of clubs that get changed, not weights in shaft as that would not work right. they charge $13.75 per club + tax. $14 postage for a set of clubs. = about $150 for a set of irons. dont know about cclight shafts as cant find them listed but cclight shaft are desindned to hit ball high.
