To me the FG's best use case is when your leader material is thicker in diameter than your braid (like 25% or more thicker), and really no other time. And honestly a blood knot or uni-blood cinched tight with gloves is plenty strong and comes through my guides as easily if not more so than the FG so I just don't fuss with it much.
I know, I know - it's stronger than other knots and all that, and I agree!, but life is short and bass just don't pull that hard in the grand scheme of things
