Hey, Robin. Honestly, I have no dog in this fight. I don't personally use Moori tips, and it's simply because there are other tips I happen to prefer. That said, I wouldn't be against trying them again as the one I used was apparently some old 5 layer tip, and maybe the new ones are different, but I'd have to know what I'm getting first.
But I don't have any reason to believe Mr. Moori did anything like this, though I also have no reason to believe he didn't. And there seems to be a lot of good information out on Barringer's site about it, but half the people I talk to tell me he's great to deal with and is a stand up guy, and the other half are not so flattering. These are all people I trust, so it doesn't really help clear anything up!
Honestly, this is just entirely too much drama for a cue tip.
