Been a while since i posted, but thought i'd chime in.
I had my 4th Kamui Black installed on my WD700 shaft (it was my 2nd SS). I have a SS on my OB-1 shaft that plays great! The one i have on my WD700 shaft has been very inconsistent. I have read in the past of people complaining that they get a lot of miscues out of the Kamui Blacks and i thought they were crazy, well it's happening for me now with the tip just put on the WD700! I use Blue Master chalk, the tip holds chalk well but i miscue like never before, I just don't get why. I've gotten out my Cue-Shark and worked the tip numerous times tapped it and all still no help. I am about to cut a chunk of the tip off and try that see what it does. I may have just gotten a bad tip but I hope what ever they do with the new version helps with others who have this problem. The 3 other Blacks on my 3 other shafts play awesome and never have given me any trouble, hold chalk great, hit great and keep their shape!
