You should consider sourcing the fur from Canada, not the US.
Wolverine is the best of the best = your breath doesn't condense as frost in the cold (-20C and colder).
Wolf and/or coyote look nice as the hairs are really long. Lynx looks the best but the price is obscene.
Just exactly how much length/width do you need? Would you settle for smaller pieces to sew together?
PM and I'll ask the local trappers that I know.
