Matt, I have a SuperCat float tube and I think they are the best craft available for flyfishing stillwaters. Use the search tool on this site for "supercat" and read the posts. They are expensive, but if you start with an inexpensive float tube and then upgrade to a pontoon boat you will spend more in the long run. You get what you pay for. Several people have had their SuperCat for 12 years. I purchased mine in 2004 and I have no desire to even look at another float tube or pontoon boat. If you enjoy fishing stillwaters you won't regret it.
