I have 500 hours in the dutchess and I must say that it has good crosswind landing performance. I find it much easier to to land the dutchess then the C-172 in a crosswind.
I use a combination of the crab and cross-control. (crab in the approach crossed at the last part of the landing).
The dutchess is a very stable aircraft sometimes when I was experiencing strong crosswind or if I was heavy I used only 10 degrees of flaps or no flaps. This will increas the aircrafts responsivnes. Another trick that you have to try is to have a little bit of power during the flare (the throttle just about 2-3 cm from idle) and close the throttle at the last part of the flare, if you try this youre landing will be perfect and you also increase a little bit of rudder effectivness.
The dutchess is a wonderfull aircraft with a little bit experience you will love it.
