Deerhound development stage 1

I wanted a fly I could use at the start of the season. I will have to concentrate on the photography because the photo does not do this fly justice. The rib I saw Davy McPhail use in one of his flies.
Hook: Kamasan B175.
Body: Black seals fur.
Rib: Red holographic with pearly on top.
Wing: Black dear hair.
Head: Black claret hare and seal mix.
I am not sure of the purpose of the deer hair on these heavier hooks and I intend to use fur from the dogs to see how that works.

Keeping it simple.

I thought I better record my Deerhound flies because this is the last one in my box. It is tied on a size 10 B175. I normally prefer smaller and lighter size hooks. I have been developing theses successfully for a number of years. Nothing startling in the tying, but fish takers in the summer months.
Hook: Kamasan B170 or 175 in a variety of sizes depending on conditions.
Body: Flat silver tinsel.
Rib: Silver wire.
Wing: Natural  deerhair with 2 or 3 strands of Krystal Flash.
Head: Hare's fur.
The fly should be slim like my dogs.
