Okay, I will be the different one. I use a double Davey knot and have for a few years. It is very fast to tie, once you've practiced it some, and it is vey strong. I really like it because it is a very small knot and easier to get two of the knots at the eye of the point fly. If you don't tie the knot correctly, it will pull right out when you go to test it.
