I can only give you high praise for these boats. Some of my information might be outdated but these have/had the most durable material of any pontoon on the market. The frames are also great and I wouldn't be afraid to take these on any trout or steelhead river.
I'm looking at getting the guide model myself and after talking with Bill a number of times I think that's what I'll get because sometimes I just don't want the hassel of taking the driftboat when I'm by myself.
If you decide to get one tell Bill that Shannon from REI here in Bend, OR sent you.
