Yep. I've tried 'em all too. Stopped looking a couple years ago because I found what I feel is the best. I use it on feathers, vanes and inserts. Gorilla Glue
Super Glue (not their regular glue). It contains rubber particles to keep it flexible and and to absorb shock better; therefore it is perfect for fletching and inserts. It has yet to fail me. The applicator tip is good for the bead and doesn't clog either.
