Todd, as a fan of shorter rods, I'd opt for the 6'6"
model. I'm a kayak fisherman who prefers the
shorter models for the areas I fish. I don't need
the length for greater casting distance, etc., and
I prefer the accuracy -- in my experience -- of
shorter rods.
But that's me. If you're bank-bound, those extra
inches in the 7' will give you a little more sling to
your bait, not sure how much, but physics....
If you're looking for a do-it-all, MH.
