I have noticed alot of guys on here that use lines of 40-80lbs test. My question is are they really needed? Most of my flatheads have come on 20-lb test mono, ocassionaly I will bump it up to 25-lb test. I also fish rivers with current, I cant ever remember a flathead ever making a run of over 15-20yds...Even the 55 -lber I caught last year came on 20-lb test. But I do have a idea, when I catch a big fish it is usually at least 80yds from the bank, I know mono has alot of stretch so maybe the fish are fighting more of the stretch of the line..I know I dont try and horse them in either so maybe thats some of it....Are these heavy lines used to horse fish in quickly away from snags? Or do you just feel more comfortable with the heavy line.
