I play with 2 shafts z2 and ob1 both sporting a kamui black soft. they are great tips, and have incredible action(when they want to) almost seems like they have a mind of thier own, that can be attributed to the high pace i play at where im almost literally running around the table waiting for the cb to stop to take my next shot.
I clearly know its all in the user when i say "they have a mind of thier own" Just tonight i went to my hall with some diffrent drills and stroke methods to try out. I have been having the glazing problems with my z2 with the soft on it. Simple fix, sounds dramatic, shape it down a layer or 2, for me it seems like with my style, im pounding this thing down with some times silver cup grey masters just now am using blue diamond, i shaved off the top layer(theyr are 10 of them too tall anyway) and i tried some diffrent stroke teq. and cue control. I belive that all tips glaze, this may more than others, and the gator grip is very worth it, metal mesh that feels sticky when you just touch it. i was a non beliver of the tool as well.
To summarize if it is glazing, either use the gator grip and take it down a layer and try diffrent chalk. If that still doesnt work, think about your stroke, this is more than likely the culprate. Im not all bout the names, i just use what performs best for me, and kamui is the only tip (non-chalked) i can give english w/o miscueing. dont ask why i tried this.
If you are still having glazing/miscues, not scooping the ball off the table that is your stroke, you may have a faulty tip, or they just are not for you if so kamui has a large fan base and they will do just fine without your purchace of the next tip. And please just because they make 25dollar chalk dont stop buying thier other quality products, seems they got swept up in thier own popularity, and thought they could fool people, but when it drops down to 10 or so a cube you all will buy it just like blue diamond./nir/magic etc. to see how great it is, it even had to be tested independently to see if it was really chalk, so it seems diffrent.
