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.
This is very good thread. I am looking at older model Mirage sport 2009 for my wife and second yak for me to use in small creeks ect... I have seen a lot different options ect... I am 5'9 195-200lbs with 30 inch inseam. Would I be to heavy for this yak I would use for fishing as well. My Wife is 5'3 115lbs, would the sport be easier for her to handle than the Revo 11 which is easier to load and portage with a cart. Any regrets to getting Revo 11?
