I would highly recomend not shooting 80#. If you are on fish all day you are gonna be tired real quick. Also less lbs makes for a faster shooter and you won't be shooting through fish. Shooting through fish sucks because you have to waste time trying to tread your arrow back through the holes. A real time waster when your shootin tournys and gets real anoying to deal with. I guess if you had to shoot 80lbs I would say get either some carbon reinforced glass arrows or alumiglass arrows or even the full carbon arrows. WCL
