Testing Kayaks for Flyakking

I went to ACK to look at Kayaks. Going to rent a couple to take out in one of the bayous here in Houston. Most likely Buffalo. And, Saturday morning going to take it down to some salt water. Any suggestions, comments, thoughts, want to join? I am renting a Wilderness 135, and if my friend joins me, going to rent a 115, as well. Wanting to test a few out.



Also, one of the guys there was telling me he uses a canoe more than his kayaks, now. Prefers it for weight limit, and ease of standing. Any thoughts/comments on canoe experience?
