I've never been accused of being horizontally-challenged, and I've never had any difficulty with the fit of my Guillemot. I'm 6', size 11, and probably 205 lbs with lungs full of helium. I'm pretty sure I built the cockpit to the specs in the book, and I have no trouble slipping into the seat. You should have no trouble.
