It enters the water very softly but instantly rockets to the bottom. It also rides hook point up along the bottom with a tail that sticks up to tempt the carp. It has a buggy look when wet that not many small cray flies have. It comes in 4 colors. Great for bass, panfish, trout, and other flats species as well. Yes, with it being tied on the Gamakatsu SL45 it is perfect for Bonefish and Permit too.
