I am considering a Titleist iron fitting as my son has fallen in love with my T100S irons. I have had these fitted at Golf Galaxy 2 years ago. My driver was done by a Titleist fitter last year and was very happy with the process. My question is if you do iron fitting is it just a 7 iron and then the whole order is based on that club like the indoor fitting at Golf Galaxy? The process was ok but considering a combo set and do not see how you would know that is what you want based on one club to determine mixing a set. Would appreciate anyone with feedback from their Titleist iron fitting experience. Thanks
