Kamui tips are the only tip I've ever used that I can replace and immediately play my game without an adjustment session to get used to the new tip. Seriously, any tip I've used in the past, I've always had to play around with for at least an hour before I could really get a grasp of the deflection, timing, spin take, and speed.
With the new Kamui tips, I have no problem putting one on after I get home from work, and taking it to play in a tournament the same night without having hit a single ball. Agreed, probably more mental than anything..................but mental is huge for me. I'm the kind of guy that can literally fold if a guy tells me "I think your tip is making a funny noise like it might be loose." or "you're not getting as much action as you usually do............could it be your tip?"
