Joel;
Sorry, if I get this wrong, but I’m not all sure, if you’re asking about "strictly buying a kayak, or, some other flotation craft!?
You mentioned that “you’ve tried pretty much all of them”, so I’d ask myself: “Which did I like, using the best?” and “Which craft, did my BRIDE also like, using the best?” Also, transportation is a big consideration, when deciding on a flotation craft. Car roof rack? Trailer? Etc.
Just my OWN, opinion, (which is all, any of us can offer, of course!), is I love my pontoon boat, out of all the other craft I’ve owned and fished out of. It’s very light, white water approved, (to class IV), and fits not only onto the $10.00 homemade roof rack on my Honda CRV no sweat, but also into it’s own backpack… including the oars and hand pump! (It’s 5 ply, 8 foot, 365 pound capacity craft)
I sit much higher, than in a kayak, on my pontoon boat,also allowing, (for me, anyway),more and easier rod control when casting, and/or, mending a line. I can “look down upon” my fly line on the water, not “across at it”, like in lower craft.
When not in use, (very rare!, but, there ARE times!), it’s also a LOT easier to stow away, than a hard shell craft. If I get REALLY lazy, on a hot summer afternoon it also handles a 38 pound thrust trolling motor and battery very easily!
I loved playing in the kayaks I’ve owned, over the years, and for speed and agility there’s nothing finer! But, l just found that my “tooner”, was a lot more versatile, easier to transport, afforded more comfort and other, options, I didn’t have with my hard shell boats!
