My 2 cents:
A long time ago I was a Twin Otter copilot in Labrador and an opening came up in the left seat of our Queenair. I had 1500TT with about 900 copilot on the Twin Otter and Queenair and around around 350 instructing on Cherokees. My competition had about 2200TT, all right seat on the same plus Cansos. He also had more time flying in Labrador than me. The chief pilot was a wise old Mosquito driver from WW2 and it was his decision. We were both surprised when he gave me the nod. As far as he was concerned command time was paramount, even if it was on Cherokees.
I guess the message is (my opinion) get the command time above all. Far better to have 1000 hrs on Beavers/Cessnas than a bunch of right seat turbine time only. That'll come.
On the less practical side, your best memories will be of flying in the bush. I've been with the majors for 18 yrs now and very enjoyable it is. But flogging around the bush in Labrador is the part I remember best.
Best of luck
