Sean,
I am 5'8" and 170 lbs. soak and wet. I bought the LE which has a 20 inch wide fuselage. I figure this is perfect for me. If I wanted to add an inch or two to the width during the build, I could probably do that with no worries. If you want to see what that feels like, sit in a chair and use a tape measure to see what 20 inches wide looks/feels like. As others have said, if you need to place the overhead tubing an inch or two higher for better head room, you could probably do that too.
I am reasonably confident in the choice I made. I hope this helps as you evaluate your choices.
Vince
