The Sniper would be one of my first choices in medium soft layered tips. Kamui soft and Moori soft would follow close behind. What I like about the Sniper is that it plays more like it did when you first put it on a month or two later. The other two tips hit changes a little more as they break in. Kamui soft plays lights out when first put on. If it could maintain that exact hit it would probably be my favorite. But more of those who try the Moori soft seem to be the ones who stick with it. I think more people who like that little extra grip on the cue ball stick with Moori soft or more technically called "Slow" than any other layered tip I sell. But for some reason the Moori medium is still the number one selling layered tip.
The top non layered medium tip is still the Triangle, provided they are double pressed before installing.
The synthetic Ninja tip is catching on in our local area. It plays a little too hard for my taste. But if you use a tip pick on it regularly it will do anything you want it to. If not I miscue too much. My son on the other hand is placing in pro events using one and almost never miscues. It has really powerful draw, side spin and follow. Those who like LePro tips like it. But I am more of a Triangle man so it is a little hard for me.
