There is a 'Hi-Top' option for builders, which adds 4 inches of headroom; the standard fuselage is tight for over 6 foot (or 1.8M if you measure yourself in metric) pilots. The Hi-Top has the benefit of a better view ahead on the approach.
The trike u/c version is easier to handle, taxi and has no more drag than the original mono. You also have a landing flap setting (on the monowheel flaps are linked to the wheel and either up when the wheel is up or a compromise flap down setting when the wheel is down).
