If you are talking about the one by Trout Unlimited, I have it but not the XL. I like it. It is very stable and works great for any river I have been on in Michigan. It does take a little work to get the hang of inflating the pontoons though. As far as using it for still water, you would be doing a lot of rowing unless you are planning on using kick fins too. I have found it works best in moderate speed rivers. Hope this helps.
