Re: Over Hang Question
As your casting skill improves you'll be able to carry more overhang. However, if you go to a slower rod you'll have to decrease your overhang. Also, when you change lines you might have to change your overhang.
Too much overhang and you won't be able to generate enough line speed and your loop might not turn over. Too little overhang for the amount of casting power you use, you'll probably get a tailing loop and/or the front of your fly line might land in a ball.
