I have just learned (last six months) the FG. I just ordered the Daichi Seiko Knot Assist 2.0. It's sole purpose is to help tie the FG (it acts as a pair of hands to keep line taught while you do your wraps).
I will say though that I have always used a blood knot on braid to mono/fluoro when the diameters are similar and never had a problem. Landed a lot of redfish, black drum, and trout with that knot. The problem with the blood knot is that it is hard to tie right as well.
The guys at Salt Strong ran some not comparisons (playoff bracket style) for different types of knots - so check that out.

Think they cover everything except the knot Shaw Grigsby shows on youtube (type Shaw Grigsby fluorocarbon knot) and the Power Knot (there is a nice picture on the web of this one --- look in images).
Fred Roubanis has a video of joining Gliss to fluoro ---- you can google that if you need it -- it may be covered on one of the other sites.
After going through all of these, I picked 3 knots for every situation and wrote them down on index cards. I still need to reference something on a few of them from time to time because I do not use them all often. Some are stronger knots, some are easier to tie, some are better for different materials, etc.
