CurtnAz,
Let's see..... to answer your question. Truthfully, all three are
awesome yaks, each individually different.
My first was the Outback. Pros: It was incredibly stable and roomy (I am 5' 10" 220lbs). I fish mostly flat water i.e. Small Nova Scotian Lakes and not much deep sea. Feature laden and customizable.
Cons: Wasn't the easiest to paddle due to it's width, hard to find saddles ror roof rack that will fit as the OB is a deep and strange shaped hull.
Second was the Pro Angler, Replacing my OB after the mover company wrecked it.
Pros: Super fishing design with tons of room, incredible fishing options/features and upradability. Super stable, could stand up in it for fly fishing. Very dry cockpit. The cadilac of the Hobies.
Cons: It is more a boat than kayak, quite slow in comp to OB or Revo, forget paddling, weight (The seat weighed almost as much as my Revo

), price and also next to impossible to fit on racks of vehicles smallerthan a mid size SUV.
Most recently, the Revo. Purchased after selling PA due to torn rotator cuff(not from the Yak) and selling my toys to try to purchase waterfront land. I got the Revo over a new OB only because there were Revos in stock and I didn't want a lengthy wait for an OB.
Pros:fast, easy to paddle, fairly stable, lighter, easy to load, easy to find roof saddles...if you even want them.
Cons:Smallish cockpit, tippiest of all three, not as many cool fetures as the PA or OB.
At the end of the day if I had to choose one for the type of fishing
I do, I would get another Outback with Turbo fins and larger rudder. If I had waterfront land that I could just walk across the lawn and drop the yak in the water or always launched from a boat launch/beach I'd probably go with the PA. The PA was just to much of a beast to haul thru the rocks and stumps to my favourite fishing spots.
Hope this helps, just my honest opinion. If there is anything else you would like to know, just ask.
If at all possible, I'd try all 3 for yourself, considering not just the fishing but also the movement/transport and storage of them. Even if you have to set up a date with a couple of the guys on here in your area to do it.
Hopefully no one takes offense to my comments, I did love each one and I'm sure my opinion would change if my circumstances/fishing style changed.
