REE,
I have seen them in action on my local rivers and they do look like they would be easy to navigate the rivers here. They are like all other crafts in that they do have their disadvantages and their advantages. I have owned and used canoes, flatbottom boats and a Hobie Cat 75 and they all have their place in my fly fishing. I strongly urge you to demo one where you plan to use one before commiting to owning one to make sure it is what you want and need. The only reason I have not been interested in them is: They do not navigate grass and weeds very well, you can only navigate forward so you would still need the paddle on board somewhere and the biggest disavantage, for me, is that at my age, I do not want to be sitting on the bottom with my legs straight out in front of me because, after awhile, it would get to be very unconfortable for me plus I would feel confined to one space and could not move around to get more comfortable. I, also, like to be able to fish from it and you will be restricted to fishing only the water in front of you. It would be difficult to fish water on each side, without twisting around at the waist and fishing that way and you would not be able to fish any water behind you. Now if you only want to use the craft to go up and down a river and get out and wade fish, it would work great. I want to be able to fish from mine, sit like in a chair with your feet on the floor, have the option of a swivel seat so that I can swivel side ways to fish water on each side or turn all the way around and fish water behind me. I can do all of this in my NuCanoe and it is very easy to navigate with it using a double bladed paddle. Trust me, I am not trying to sell you a NuCanoe, I am just trying to explain why I can do more with a NuCanoe than I could with this particular craft and that gives me "more bang for the buck".
I strongly urge you to demo anything you plan to purchase to make sure it will do all the other things you want to do in it besides go up and down a river or lake. If you do not plan to fish from it from all angles and do not mind sitting on the floor with your legs and feet straight out in front of you for extended periods of time, it will probably work just fine.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
