I am flying to Mexico next week and need to change the line on my reels. In the past this was no big deal, take 'em to Turner's and let them do thier thing. Well now I live in CO and the largest test line in bulk is 12lb, plus I have heard horror stories about carrying on reels on the plane full of line (I usually drive). I have decided to put the new line on the reels the night before fishing, my question is: what is the best knot to use attaching the line to the reel?
