i must say i love my Shimano Jigwrex
they have a model in PE5,PE6,PE8
i have the s605 which is 6'0" rated to 300gm jiggs and PE5 i run 50lb on it
as Big-Banana said running 80lb on a PE8 rod if you connect to some thing big enough its going to pull you in
im not a small guy im 6"4 and i think i would even struggle holding onto the rod when fully loaded up
and in all reality i dont think your ever going to need all that power
