Hey Volvo, I thought they were the same thing until I googled them and I see there are few videos that tie a GT that involves a figure 8 in the mono and a double in the braid (via a bimini). All news to me, i pretty much use the FG all the time now for braid to mono, thing i like about the FG is that its essentially a splice, not a knot. GT (the ones i saw on the net anyway) seem to be more of knot to me. I'm an FG fan, knot that I've used the GT...
