What is the best and smallest knot that can be used to tie a 50# mono shock leader to a 20# mono running line? The challenge is getting the not to flow smoothly out of and into the level wind (Abu 6600). I currently tie a regular overhand not in the leader line and a uni knot in the running line. I know the easiest fix is to go conventional, but, as was suggested on this board, I need to get comfortable with the level wind baitcaster before I move up to the conventional.
