I’d like to keep the heads, for now at least. Putting new shafts, grips, etc. would be worth it I feel.Fitting has different meanings to different people. Most people aren’t going to reshaft used clubs. Most likely they are going to put a piece of electrical tape on the bottom of the club and have you hit a lie board. They will bend the hosel to get the mark in the center. That isn’t fitting to me but better than nothing. Forged clubs can be bent with little issue. Cast clubs can break when bent and a lot of shops won’t bend them. The shaft to me is just as important as the lie.
If you are married to those heads and money is no issue than by all means reshaft them if that is needed. To me it would be worth it but that’s me.
