a few things I've learnt with bullie flys, all of these statements are experience driven:
sparse is better
Heavier is better
big bullies like other flys than just streamers
only one hook is needed and the smaller the better, the bully in my avatar was caught on a #6 Gamagatsu Octopus.
Bullies typically hit fish or fish imitations from the side, they mash them up in thier mouth then take them head first, therefor they tend to miss the first hook and hook up on the trailer when you set. To me having an additional hook can negatively impact the bullies.
Jayvee lets hook up and I ll show you how to tie the Matador
