I have a St Croix Premier 8 foot medium-heavy rod that I have been very happy with. I am considering getting a heavy action rod for use with heavier baits. St Croix has an 8 foot and 8'6" rod available in heavy action in the Premier series. I am leaning towards the 8"6" version but wanted to hear what other people would recommend. Is there any disadvantage to a longer rod? Thanks!
