When I say fight I don't literally mean it...
But it is a fact the XLS is not as docile as other planes in the initial climb phase.
With the trim set slightly forward than the central position (still within the limits for TO of course) and the appropriate speed you can minimize the effort, but the manual trim is an option only if you seat on the left... the manual trim is only on that side, and if you are the FO you really are not in a good position to use it while handflying. The electrical trim is not very fast.
The baggage hold I agree is great: we regularly fly 6 people, each with golf clubs and baggages, with no problem whatsoever.
