Tied it with 100lb spectra still a small knot
My bad Misread the post too fastYou are talking about a spectra to fluoro connection. He is talking about mono to fluoro. I prefer the John Collins knot in that application. Much easier and you don't have a knot around the spectra. Those knots tend to hang up as the fluoro leader diameter goes up.
