Care to elaborate? I'm not going to go nuts - Some people just don't like 'em. If you happen to be exceptionally wide in the butt, it's probably not gonna be comfortable. Beats the hell out of a PA28, though... I get a backache in those after about 1.5. I flew WI to TX and back in the DA40 already, and was pretty impressed. It did start getting a wee bit uncomfortable for me on REALLY long legs, but as long as I got out every 3 hours or so I was fine. Someone who's not as big as me would have a much easier time of it - Less weight on the seat, and someone who's not so tall could put something from Oregon Aero down (I'd be hitting my head on the canopy if I did that). There are certainly some "quirks" in the design, but none that I would consider negative overall. For example, the way you check the fuel level on preflight is weird, but it's that way because of the long, skinny aluminum tanks that are contained between dual main wing spars - And they are that way to make the airplane as safe as possible (note that Cirri tend to burn upon crashing - Diamonds just don't). So I'm okay with that. The non-movable seats and movable rudder pedals, likewise, are a design choice - That's what allows the center stick and ergonomic cockpit layout. I *really* like the stick, and the flight characteristics, it's a delightful plane to fly. So I'm OK with having to move the pedals. So, two questions - What do you consider "more amateur" about them, and what are the design quirks that you think make them suck?
