The PTM is a universal hosel, meaning you can use .355 or .370 tip shafts. If you use a .355 shaft, the 65TI ferrule will work. It’s a 1/2″ black ferrule that we use often. If you use a .370 tip shaft, the 60PI is the .370 version of the 1/2″ black ferrule. Swing weight, at standard length should be around the D1 range, based on 49 gram grip weight, 115 gram shaft weight and standard head weights.
