In Newfoundland the abundance of caribour hair makes its way into tying so much. As there are no deer on the island most every tyer I know tied spu hair with caribou. That said, it is perfect for spinning and I find it very durable. For example. Buck bugs, bombers, are mostly tied with caribou and when packed well it floats incredibly well and withstands all sorts of abuse from Atlantic salmon. I also use it for wings on some caddis patterns. I believe there is a video of davie mcphail tying a caribou caddis. They guys are right, you can't use it like elk hair, but you can use it like caribou hair. Tie some elk hair caddis with a caribou wing, they work well and float well too. The only issue with the hair is that it is much shorter than deer or elk.
