I have been slowly moving to Kamui clear soft on most of my cues. I wont change a tip if i don't need to though. if it is on the cue, and has clearance, i leave it alone. I moved to soft because i find i over hit too much with hard tips. my buddy is the opposite, it under hits with a soft tip so he plays with a hard tip. we will swap cues once in a while and the games we play tend to go downhill quickly
I have yet to replace the first kamui soft installed 2 years ago. it has hundreds of hours of play on it. still looks new. while definitely pricier, if one tip is lasting me multiple years, i don't mind the initial cost. I scuff it once in while, but that is all the maintenance it has needed. I have had more issues with leather tips than the layered. both have their pros and cons. I really like the sound a kamui soft makes which is the main reason i use them.
i was a triangle guy for quite a while. then on my player i couldn't figure out why sometimes my cue was hitting really well, and others times not. apparently after investigating there was a air bubble in the triangle. it was so inconsistent to when it affected a shot i had no clue. maybe one in 10 shots felt weird and sent CB off in a crazy direction. when my installer removed it he showed the me the bubble in the middle. I had heard stories, but never seen it.
i did love the older Mooris, too bad they were changed. those were my go tos.
