How long would a moderately used (2 rounds a week, say) set of stainless steel irons stay in adjustment? These are the old Glider Xs that has short hozels. They seem to be pretty close and been used steady for 5 years. I was able to find a new set from one of this forums contributors so I know the age. I don’t trust myself or anyone else to try it. What does anybody think. Thanks.
