I feel that most layered tips play best from the middle down,so as a player I've been taking at least the top 2 layers off,and then start my shaping. The tip currently on my main shaft is a medium Ultraskin.
This also applies to Kamuis when I've used them.
I also suggest the same to customers,some agree,some ask for that specifically,and some want it full height for longevity.
The last non layered tip I installed for a customer was an unpressed Elk Master,left as tall as I could to go along with his new ferrule. When I handed it back to him,he looked confused and asked why I cut so much of it down,LOL.
On the other hand,in one of the few times I've talked to Alex,he came up to Joe Blackburn's booth with a rush job,and at the time he was still using his old stitch ring Schon with a Predator shaft,and he wanted his Moori H cut down to half height THEN shaped,leaving a sidewall barely the thickness of a quarter.
