I'm about 3 hours from Vancouver. A bit far to test sitting on but not to bad to meet up for a sale. If I were you I would call Summit at Whistler and talk to a few of those guys. They probably have a few in stock and also they know sizing really well because they rent Flatlines all summer. My gut as a shop employee is that it would be spot on for you with a 55mm stem, as one of the other employees is 6'6" and that is his setup. Let me know if I can get you any more info!
