I had some original Moori tips when they first came out and were all the buzz, hit great. I bought a Ned Morris cue, one of the tips was a Moori but older, that shaft hit great. When that tip had to be replaced, I bought a new Moori Soft, blah! Hit harder than the old tip, no feedback at all, mushroomed daily, did not grip the cue ball. After a few months I put that shaft away and used my second favorite one, but at least it had a better tip on it.
Replaced that Moori with a Kamui Black Soft eventually since I kept reading here they were the nuts, best tip I every played with in over 20 years. All of my shafts have Kamui Black Soft tips on it, played with one for months, it looks and feels like new, no mushrooming, keeps it's shape, needs a scuffing or picking maybe once a week or two.
