Good visibility, fairly comfy if you're not real tall, easy to fly, built like a bridge. I've enjoyed my time in it.
Trailing link gear makes for excellent landings, you have to work really hard to get a bad landing.
Be careful on the brakes on landing, you can brake really heavy and stop real short if you're careful, I've put it on the numbers and stopped it in 500 feet without locking a wheel, but if you absolutely stomp on them you'll blow tires repeatedly, and that makes your mechanic angry
Always make sure to open the little door for the emergency gear extension valve and make sure the valve is closed (perpendicular) before your flight. We've had the same instructor TWICE forget to close the valve after doing an emergency extension demo and the next person who flies the airplane burns up the gear motor because you select gear up and the motor just keeps running.
Please be nice to the gear doors and avoid putting the gear down right at the gear speed if you can help it, the main gear doors are just sheets of aluminum that attach to the gear legs and they crack... repeatedly... from people throwing the gear right at the gear speed or even slightly above (Don't even try to tell me you don't

) Give yourself a 5 or 10 knot buffer, for your mechanic's sake
Be real gentle with the fuel strainer sumps on the side of the engine cowling. The fuel strainer bowls are "composite" (read: plastic) and if you put side load on those sumps you risk cracking the bowl or the associated hardware, and them bowls aint cheap (see the airplane buying thread).
uhmmmmm.... OH! Do NOT pull the pilot's door shut by opening the storm window and pulling on the frame... I've replaced like 323525234234 pilot door windows because someone does that and cracks the window out from the frame.
On the same token, most Duchess doors are slightly bent so do give the door a good shove after you close it to make sure it's actually latched and not going to pop open on takeoff. If it does pop open on takeoff don't freak out and do come back and land before you try and yank it shut with the storm window (see above).
