Man, oh man, You guys are way to physical for my taste, (or condition). Since I blew out the L-4L-5 & the L-5S1 discs in my lower back the best I could possibly do is to row for awhile, maybe, ...well no more than about 2 &1/2 hours solid. Then I'll be almost completely worn out, & in some form of severe pain. But then, that's why I bought two trolling motors, mounted one up front for steering, then mounted and ran wiring from a switch up front to the one in the back. It's a helluva lot more convenient, (once it's in the water), but increases my gross weight of the craft alot. So there is/will be a trade-off disparity if I am forced to portage around any logjams, dams, etc. Still, I think I'll take my chances, if I stay in Indiana, I can fish a number of lakes/impoundments or the streams & smaller rivers here, or if I decide to shoot over into Illinois & put in on either the Fox, Kankakee, Vermilion, Illinois, or Rock rivers. There is great fishing all over these rivers, lakes, etcetera, in many areas, & the different species are as varied as are their numbers. I guess it all boils down to if you're comfortable with the fins, & you're going to putz around a lake, then go for it, if you're going to run moving water then maybe you'll need both, or if it's got any whitewater, you might just want to get familiar with a good set of oars. I would definitely consider any/all safety options first & foremost, prior to making any decisions about going out on the water. It'd be even more helpful if you had someone to pair up with the first few times that you venture out on the waters anywhere, or at least till you become familiar with the area's hazards/attributes, as well as your craft, & all of it's little nuances. Safety goes hand in hand with having a successful trip, it is the essential equal in the planning of your outing.
