One of a hundred million variations of the now internationally famous shrimp pattern from el Big Yin 'imself Mr. Ally Gowans.

The DressingHook: Partridge Salar Silver Size 7
Thread: Black
Body rear half: Medium silver tinsel
Body front half: Black Straggle Ice
Rib: Medium silver wire
Hackle: Mixed orange and yellow hen
Wing: Mixed orange, yellow and black bucktail
I really like slim tied flies, that one would also work well for loch trout in smaller sizes especially if the silver tinsel was replaced by gold.
