This Templedog pattern is a big favourite in Iceland and Norway but it can be used anywhere where the signature shape of a Templedog works well.  One of the best patterns for when your fly needs to have presence in cold or coloured water conditions.  This version is tied on a plastic tube so that it has minimum inertia and therefore maximum movement in the water.  Vary the depth it fishes at using sinking tips to suit the speed and strength of the current.
