I agree - the best place to tie knots is in the house, not in the dark on a lumpy ocean in 30 kt winds (ask me how I know this). I tie a snap-swivel on my main line. I pre-tie 18" leaders on all my jigs and lures, with a small surgeon's loop on the tag end. All I have to do is un-clip one lure, and clip up another - easy...and the fish don't seem to mind. 3-ways shouldn't be a problem.
I use braid for everything.
