I saw a post discussion on open water – But – Which would work best for use on rivers – Class 1 – 3 water (Class 3 minimal) for fishing floats. The floats will be 4 – 20 miles depending on river flows. Could be very little flow with many shallows or high. I have never used either, having fished canoes with two persons typically. Now fishing single (son in college). If you recommend a Fishing Kayak, which type for moving water that can fish fly rods and small spincast? Thanks!
