My suggestion would be to bring your current set of irons with you during the fitting and hit old club versus new to see what the changed are, see if you really are getting what you want from the new irons. Just a thought.
Wish I was in the market for a new set of irons, I loved the shopping and experience of searching out new clubs. But I just bought my Clevelands so....
Myself and the guys play with are over 65 with various ailments, we don't drive the ball that far either. In NY where we play with have blue, white, gold and red for the ladies. We most always play from the golds, i.e., play it forward, to speed the game up and not hold anybody up behind us. We're out there to have fun, it really doesn't matter to us that we play the gold tees.
In the league we are in if you are over 65 you play from the golds.
We all want to get to the 19th hole as quickly as possible.
