Dan,
Hopefully I can help in your decision making but ultimately whichever kayak you buy should be based solely on your own opinion and comfort level. Having owned both a revolution and two outbacks I must say that these are definitely different yaks. Many will say the speed of the outback is noticeably slower than the revolution and others will argue it till they pass out. I would say that the Revo is definitely quicker on the water if you are paddling (not peddling) in comparison to the outback. The outback is a freak of nature and is extremely wide and very very stable. The revo is much more maneuverable on the water and getting through the surf quickly. The type you choose should be driven based on the type of fishing you are going to be doing. If you are looking for a yak that you can stand up on and cast off of then the outback is superior. If you are looking to peddle and paddle around and get through surf then the revolution is better. It all just depends on the fishing you are going to do. If you are pulling up monster size fish constantly like Josh is then get a pro angler. Josh has one because he catches massive fish so he needs a massive deck to hold all is fish on!
If you are going to fish bays and lakes and not going to get into the surf much then an outback would be fine. Both are great kayaks and some swear to one or the other but they are both great for just different types of fishing. You just need to figure out the type of fishing and then definitely go peddle and paddle (don't rely on the peddles because you will need the paddle at some point) both of the kayaks around. You may just feel more comfortable in one over the other. A kayak is like a recliner.......some are wider, narrower, more comfortable than others and sometimes, if you are lucky, you wind up with something on your lap!
