Agree that the Adventure is fast. It's 16 foot and sleek compared to the PA. It'll eat the PA in a race. For fishing it shouldn't matter unless you're running from spot to spot and that's not likely in a kayak. Fish the water you're in. Ive got the PA and wouldn't trade it for the Adventure but it's because my "arse" wouldn't fit an Adventure comfortably for fishing. I'd like to have an Adventure.. I'd use it for cruising and enjoying a ride, but I have a stable now. For fishing, I've really enjoyed the PA. Don't forget "DRY"....... swamp butt..... consider that also. The Adventure is a wetter ride by far.
You will get opinions from all directions and until you try them out, you just won't know. Good luck.
x2 dry , comfortable , stable,, no swamp butt
