I have pressed some mooris with success, but you still have to be carefull and not over do it on the preasure. In general I would have to aggree with Joey about laminated tips. Some of them can't handle pressing at all regardless of how carefull you are, and it can create seperation in the layers. It's not something I would recomend, and is something you would be taking Your chances on regardless.
In general though a lot of non-laminated can be pressed over night If that's what You wanted to do. Greg
