I have been having elbow problems for the past few years. I recently purchased some new irons but the retailer gave the manufacturer the wrong specs and I received the wrong shafts in the irons. I was going to get shafts with Sensicore inserts but my doc and son's pro suggested I go graphite. I've been hesitant to do so, but used this opportunity to go ahead and get the irons with graphite shafts. I hope they work out...I've been playing steel shafts forEVER.
