Thought that I'd weigh in.
I - among others - have been using Loon UV Knot Sense in lieu of epoxy for a while no. Advantages: quick curing and nice appearance (doesn't appear to cloud up over time). One major disadvantage is the poor adhesion to the tying materials. I think that the product is designed more for "glomming" onto itself (i.e. around a knot on your leader) and not so much to something else in an "open" system (i.e. sprawled out on a feather bed...er...so to speak). Flies that others have tied which are COATED more-or-less uniformly with the knot sense seem to be less prone to have the knot sense come off. Others (um...the patterns that I'm using it for)...well...not so much. It's quick for making shell-backs, etc., but the material won't last as long as standard epoxy. Other possibilities are out there as far as quick-setting "adhesives"...in the process of looking into them and will report.
In short...it has some great applications. The company is environmentally-conscious...that speaks a lot (even you non-hippies out there should appreciate that to some extent).
Cheers, Chris
