Hey KDm, I picked up an Ocean Kayak Predator 13 last year and used it on Sak, Darling and Buffalo Lodge. It is a sit on top. It is set up as a fishing rig. Great below deck storage, built in rod holders, plenty of space to mount electronics if you want. I have paddled Audubon for 8 hours straight "trolling" without getting to worn out. Only flipped once, my fault trying to reach too far. I don't know about standing up and sight casting, Have not tried and no interest in standing up in small boats. I really try not to make a fool of myself too often. If you are in no hurry I suggest trying sit in and sit on top first. Sit in is more stable, but a little harder to get back in if you flip. The sit on top puts your center of gravity higher up, hence not as stable, but much easier to re-enter (see above). Also the whole self bailing thing is nice. Be cautious of very wide kayaks. Yes they are more stable so you can stand up but a lot harder to paddle and a bitch when the winds are up (think sail area).
