Okay so I'm getting a mcdermott cue probably after Christmas, and I'm most likely going to get the tip upgraded to either a moori hard or kamui hard. Since they're the same price, I figured I'd find out which will hold up longer since I don't really want to have to fuss with tips myself very often, and I have no way to locally get tips changed. Are these pretty resistant to mushrooming and flattening? I just figured I'd ask around, since 20 bucks is a lot for a tip. The standard tip is an everest. Any opinions on that one? Thanks, mhodar13
