I have installed Ultraskins on most every cue my wife and I have. Started with a couple softs, didn't end up liking them. Then tried medium fires, liked them a lot. Now have converted two of my shafts to Ultraskin black mediums, especially on my Jacoby Ultra wood shafts. Occasionally playing with my stock Schon shaft made me want to move up to the firmer hit of the medium black tips. I still have a couple shafts with the fire mediums, in fact one is the shaft I use in league, but it hits as crisp as the black medium due I think to the fact that it is wore down to the point that I need to replace it soon. As to Kamui tips, I only have used one, a tan soft, it came on a Jacoby Black carbon shaft I got for my Schon cues. I have to admit, I like it. The sides mushroomed out once, and after that has mostly held it's shape but it does flat spot in the center occasionally and need to be rounded up again. I haven't noticed any glazing, and even though I have a cue lathe, I will leave that tip on till it wears out and replace it with a Ultraskin as I think they are at least as good or better, and a whole lot better value.
