I recently installed a .335 tip shaft in an old CT hybrid which has a .350 hosel and forgot the shim. Do I need to pull it? Am I risking breakage if I don’t?
If you got the shaft in all the way and used a sufficient amount of epoxy, I don’t think there is an increased risk of breakage. The concern is if the shaft is centered in the hosel and if there is enough coverage of epoxy in the hosel to prevent the head from coming loose.
