The topic has come up before. Just for everyone’s info. I just reshafted G410’s with Alta CB shafts from the G425, so basically the same shafts.   There is definitely a lot of play in the hosel, in fact .370 shafts would fit with still a “lot” of play.    I used the specific Golfworks ferrules for the G410 and they were extremely difficult to push on. I had to use my shaft puller, in reverse, to do so.  The golf works ferrule installer wouldn’t fit over the collar.
