Most of my fly fishing is done in saltwater, but a couple of times a year I get to places where I can fish in cold freshwater. For years I have used the loop-to-loop connection for attaching tippet to leader in saltwater, with perfectly satisfactory results, but used a blood knot for the same connection in freshwater. As I get older it gets harder and harder to tie blood knots. Has anyone tried the loop-to-loop connection in freshwater? Does it reduce the number of takes? Does it make any difference whether it's used in cold or warm water?

Thanks for any advice.
