Head Turner,
The only c of g problems you will encounter is with 2 people(you require about 20 kgs at the rear seat station to stay inside the envelope( about the weight of an apu) if both are in the front, the more people you get in the back the better,( You really need the exec seats as you can move these backwards in 5 seconds if you are only carrying four and this also keeps the c of g correct and gives the pax mega leg room ) the biggest thing to get your head round is the shifting c of g as fuel burns, but no big deal.
Are we thinking of the same machine, they have bags(about 6 big ones LOL) of baggage space as a four seater, you can remove the rear 2 seats in 2 minutes and use all that space(or just put stuff on top of them), but you must use some form of restraint as the bags are in part of the rear cabin.You can also remove all the seats and use it as a big luggage area ( 4 x 45 gallon drums , plastic ,not steel)
A lot of people say about the yaw, all I can say is that I have flown in very blustery conditions, and never have a problem, but there is a nack of flying them, and the best thing if you are buying one is to do the course at MD in arizona, you will learn a lot about the machine, and see what they can really do
.
The B2 is a good machine , but is nowere near as smooth as the 600, they are also more expensive to maintain.
