Keep in mind that I prioritize speed, range and and weather capabilities and am not a fisherman. I'm about your size though (5'10" 180).
The Sport has the Outback's tray system -- that may be an advantage to you. On the othr hand, the Revo 11 has a bow hatch and much better interior access.
On a head to head basis, here's my comparison:
Compact transport and storage -- Sport by 1 1/2 feet
Weight -- Sport by 2 or 3 lb.
Ease of loading -- I can't tell the difference; both excellent
Cockpit space, size, weight capacity -- Revo 11 by a substantial margin
Pedaling efficiency-- Revo 11 definitely at our height
Initial stability -- small edge to Sport
Secondary or final stability -- small edge to R11
Speed/range -- R11 by a wide margin
Seaworthiness (wind and chop) -- R11 by a mile
Turning/maneuverability -- both excellent
Quiet operation -- no question the R11 has it, the Sport doesn't
Fun factor -- no comparison. R11 is a blast!
Bottom line -- I sold my Sport to get an R11. The Revo 11 is a dynamite little kayak and feels like a sports car on the water.
The Revo 11 should be able to accommodate any fishing gear add-ons (ram mounts, Scotty mounts, depth finder, bait tank, etc). It only lacks the handy trays that some fishermen like to use.
If you can get a demo first, you can compare for yourself. IMO, the Sport does a lot for its size, but the Revo 11 delivers more comfort and versatility.
