TEEm Tour Edge should be able to give you some info soon on the C721 irons. All 4 of us choose them. They should be arriving soon. Let’s us know what you would like to know about them. One member choose the rdx graphite shaft option. The other 3 went with elevate 95 steel shafts. Be glad to help you out.Currently playing the JPX 921 Hot Metal Pro and considering a set of the C721 or E721. Just wondering which one would fit my profile. Play to about a 12 - 14 handicap and a senior golfer. Always looking for more distance without sacrificing dispersion. Any thoughts?
