For anyone who is deciding between a PA and the Predator XL, here is a link for a nice "on the water" look at the Predator XL. Tony from VentureTube gives a good look at the Predator XL, along with a few other kayaks, including the PA17. His review has put to rest any doubts I had in picking the PA12 over the Predator XL. I think the vibration would drive me nuts and the overall performance just looks clumsy. I went with the PA12 mainly for its tight turning radius and I'm sure glad I did after seeing this. Love my Hobie!
