Since this thread I can also say that, 1 , I have learned that if you are using new mono, just give it a very light sand on the area that is to be wrapped, it grips like no other! very, very good knot.
I have experimented with the slim beauty knot and have managed to tie a modified "slim beauty type knot" and is just as good.
If you tie the FG in windy conditions, use the technique where you wrap with the mono, rather than braid, wind will have no effect!
