I use to cut off my loops because I thought the line was too "hingey"---- but now, for all those lines that I have cut the loops off of, I nail knot a piece of 12 or 15lb. mono to the end of the fly line to use as a butt section and then I blood knot a tapered leader to the butt section - or make a perfection loop in the end of the butt section and then loop to loop to the leader. The furled loop idea mentioned above is all I use for my Salmon and Steel head rigs when I am swinging or stripping flies.
