After reading through all the responses on this thread, I've come to the conclusion that I must be doing something wrong. I've tried Kamui's (both black and brown) along with a slew of other tips. I keep coming back to Moori. Last year I switched to Moori soft and expected some mushrooming. The Moori Soft tip never mushroomed, never glazed over, and plays great from day one. I touch it up about once a month or so with my Willard shaper very lightly and that's about it but not because it needs it but because I feel more secure doing it. When I played with a Moori Medium I experienced some slight mushrooming after a month of play - and I played with about 3 or 4 in a row. After mushrooming once, they never mushroomed again. I liked the hit with a Super Pro tip (a really hard tip in my opinion) but miscued occasionally when the cue ball was smack against the cushion. The Wizard and Emerald play like a Moori Medium and I liked them. I appear to be in the minority liking Moori over Kamui but which tip to use is so subjective. I guess that's why there are so many different tips available. So my suggestion is to try it yourself and don't pay attention to what other people use. What's right for you is what's feels right to you. Good luck in your quest for the perfect tip.
