Small
mouth - small flies!
The headline contains some truth in the sense: When
trout/graylings eat tiny surface-food, they only nead to open their mouth to a
narrow slot and sip the fly in. If one presents them with a fly with a broad
hackle - then they can’t suck it in through their narrow mouth.
Vince Marinaro in his book "A modern Dry-Fly Code", 1950 showed how he
solved the problem.
For his famous 'Jassid' he uses:
| Hook | Model Perfect, regular size 16. |
| Hackles | Two short-fibred black cock-hackles wound as a palmer up over the shank, and then cut on top and bottom, so that the fibres only point out to the sides. |
| Wing | An eye-feather from a Jungle Cock tied down, so it covers the shank. |

insects caught in the surface.
