I use spinning tackle about 98% of the time. Have been using braid with fluorocarbon leader for 25 -30 years. When I started using this combination one of the most popular knots for joining the two was the plain old surgeons knot. The modern knots like the FG, Alberto, and Albright etc were not popular (maybe not invented). I still use the surgeons knot today. I don't believe it has ever failed on a fish. I pull it really tight and trim the leader close so it comes through the guides just fine. If I get hung and break it off it will fail at the knot about half the time. Today the FG seems to be most popular. Way too tedious for me to tie and research says this knot is for dissimilar line diameters. Small braid and heavy leader. Wondering what y'all use for braid to leader and if it's ever broken on a fish.
