Last spring I purchased a set of AP2 irons with the C-taper shafts. Recently I decided to increase the swing weight by adding tip weights. Last night I pulled the head off the 3 iron to make sure that I had the correct size components before pulling the remaining heads. When I tried to clean out the old adhesive from the hosel with my .355 wire brush, it was too small. So, I measured the id and found it to be .370. I've read here that all Titleist irons are supposed to use a .355 taper tip shaft. I'm wondering if Titleist changed to a .370 parallel bore on their irons?
When I put the shaft back into the hosel, it's a pretty sloppy fit and I'm concerned that I may not be able to get the correct alignment.
