A bud of mine wants me to install a new UST Mamiya Attas International Series ISA1000 shaft in his Titleist 816h 19° hybrid. I did one for him several years ago for a 27° but I don't remember how I came up with how much to tip trim. He really likes the 27° so I must have done it right.
Does anyone have any info on how to tip trim these. I have done an internet search and have come up empty. I have not tried contacting UST yet.
