I am around 200 pounds and six foot one inch. So the widebody might be a better fit. I have been in the back of cubs, but never flown one. I climbed in a standard size cub , down at the shop the other day, and shut the door, It seemed like it had more elbow room, than my 170. When sitting next to another guy, with winter gear on it get's pretty tight in the old 170.
As far as the widebody, I was just concerned about how it handled, compared to the standard.
