We sat in one and flew over the weekend.. Im not as tall as you.. 5ft 11 and though I wasnt P1 I was back seating and with my headset on my head or top of headset kept hitting the overhead panel which was a bit annoying! Maybe not a show stopper though..
I found it to be quite stable with a good cruise speed and quite responsive and giving full power at 2700 RPM even for an engine on condition! Though we havent gone for this one.. and are still looking I did find the all round view amazing as in a PA28 you can't see didly squat out the back!
Maintenance wise I have had a chat with a few shops and the one I have in mind has 3 TB10s to break sp plenty of parts should the need arise..but agreed on what you say!
Still looking but widening the search to other aircraft.. though in my opinion TB10s represent quite good value!
