This is another must have fly if targeting flat species. Another big
producer for Permit. Fished either "dry" on the surface  or just off
the bottom with a small weight (supplied).

Tied with or without a spawn sack.
Please specify if you want a sack or without. During certain times
of the year the natural crabs have a roe sack. 
What could be better than crab with a bit of caviar?
