Ive been messing around with bumble style flies for sometime now and had some success, trying to get a few killers for Lough Melvin.
With the golden bumble, georgous george, telephone fly and melvin octopus all being bright killers that attract the sonnaghan.
Here is one with a few target points for the trout and a little bit of coral to represent the daphnia.
Its a fairly busy dressing
