This is a variant that we created of the Teviot Shrimp. This has been a good summer pattern that we have tested out on the Teviot and the Tweed and it is ideal as a summer fly, not just the pink and blue abut the wee tube drops in quickly into the water and fishes low into the water for the size of it, paired with a tube hook it sits perfectly. This is the 8mm crimp tube that is a great summer variant, well worth having for that trip to Iceland.
