I fly a tri gear and find it very comfortable even after a 4 hour flight, But i am 5'7" so below average height, as been said you can have a high top and width extension but obviously only if you are still building the fuselage,
they are a delightful aircraft to fly but i decided early on in my build that the mono wheel wasn't for me, this move proved correct when landing in a 30 kt crosswind in Finland a couple of years later,
there would have been no way a Mono would have stayed on the runway in those conditions,
To be fair to the mono they are lighter and faster and can land and take off from rough long grass far better than the tri gear, so its horses for courses as far as i'm concerned,
