RE: Loosing Blazers with a biscut
I'm assuming it's the glue or some other factor. If you are cleaning the base first, don't. They are treated w/ something that helps adhesion. Cleaning them only wipes that off.
Personally, I've never held much faith in FletchTite. When I was using that stuff, vanes fell off all the time. And I mean, all the time! I switched to Pine Ridge (but any of the cyanocrylates will work just as well) and it's no longer a problem.
