Sounds like you're a big lad... you'll find plenty of room in the cockpit, a lot more space than the average Cessna and Piper and you get your own door.
Bulldog... similar airframe, 200 hp fuel injected engine with a wobbly prop.
Probably be happier with your 19 stone.
Again has a roomy interior to accomodate military parachutes and bone domes.
One of our group instructs on Bulldogs in a University Air Squadron so I'll ask him when I see him.
