I have a good friend who just relocated from Kotzebue, Alaska. Bush pilot, flew Cessnas and other spam cans. When I asked about this subject he said he did not see a composite a/c during his 6 years at that job. As far as handling characteristics, his commented that "you need a wing that can handle lots of ice and an airplane that has mucho crosswind capability."
His comments came from a postion of flying to earn a living, not flying for pleasure and hobby. He flew in all kinds of nasty stuff...as most Alaskan pilots do. He thought there were other machines better suited for the mission, even if the a/c was hangered all the time and taken out on CAVU days only. I also understand that the reality of Alaskan VFR is just a little bit different from what we in the Lower 48 think.
Best,
David
