Can't top Eddie's recommendation (a heck of a combo) but I can add that some guys like a 9'6" for a little more reach from float tubes, but they will pay the price when bushwacking.
If you fish more from float tubes than trekking in woods, you might consider that. If you do the opposite, I have a 8.5ft 5wt that I find much easier to bushwack with as well as roll cast in tight quarters for small streams.
As a compromise, what Eddie said.
