Depends if you want this boat for just yourself or to take others with you.
12' Sprat or Journey will be trailer boats if it's a one man show - or a boat loader.
I've had all the popular aluminum small jon's for flyfishing and I have a 10' Sprat for just myself. I took the center bench out and put a flat floor and pedestal seat in place - I love it but it's heavy. I have a 7.5' inflatable for tough shallow/muddy launches or where I have a longer distance to drag/roll to. I prefer the Spratly but I really liked the 2-bench 10' Valco - that's a good one if you find one. Don't get the Valco 3-bench - it's narrow and not enough leg room.
