I don't have a ascend fs'10 but I have a 12' and mine is sit in also. When I started searching the sit in or sit on top debate made me keep searching for a sit on top because that seems to be everyone's preference. Well unless you spend more for a decent sit on top, I would buy a sit in if you are on a budget. I have a 12' pedal pescador and my 12' ascend, and I would choose to fish in my ascend all day long. The seat is pretty dang nice and with a little know how, u can mount a trolling motor on it. I did and will never look back. If you can find a used ascend fs12', I'd give 450 for it all day long.
