I started trying softer tips about a year ago. Mostly unltraskins but this is the first kamui tip since the cue came with a kamui tip. I play anywhere from 30-60 minutes around 5 days a week and sometimes 2 hours in a practice session. I do a lot of artistic pool too so that might be a part it.
I use a Hard tip, and have to perform maintanence on the tip about twice a year (almost whether it needs it or not); while the tip lastsabout 15 months; even with a dime tip radius. I break with the cue 20% of the time--generally fairly soft with the play cue.
I play 3 hours a day, 5 days a week, solo; so I'm taking a shot about every 10 seconds. Lots of strokes....
On the other hand, I can only draw back 12 diamonds wth the hard tip and a level cue. 15 diamonds with a 20 degree elevation of the but.
