I have no information on that shaft. Do you know if it is a .355 taper tip or .370 parallel tip? What exact clubs are you trimming them for? If they are .355″, you can’t trim the tip at all. If it is parallel tip (.370″) and we could get the parallel tip section length, we might be able to tell you how to trim. What flex is it? It should say on the shaft what the designed flex is.
Can’t really help without more information.
