I've been learning how to tie a Bimini twist. It is not a hard knot to tie, I just don't know if I'm doing it correctly, and then I am not sure how to use it from that point on.

First, after tying the knot is there supposed to be any slippage of the tag end and loop on the main line (as when you hook up with a fish) or is it a solid knot.

Second, so I have a twist and it is a double line. How do I fasten a fly to it. Do I use a Palomar knot at the end of the loop or do I tie on a piece of tippet (with which knot).

How is this knot beneficial if I have a single piece of leader connecting to the line and on the other side I have some other knot that is less efficient.

I am confused and await enlightenment.
