There are a few different ways to tie a Double Bunny streamer and this method for the Baby Rainbow version has a few interesting aspects that I don’t normally take into consideration while tying my own. The shorter belly (gray zonker) is a clever modification that will ensure the fly retains much of its natural movement. One other small adjustment I would try is to tie the flash behind the brass eye as you tie down the zonker. I don’t think that having the flash tied in at the head will have a negative effect, but rather having it tied behind the eye will allow it to swim at a natural lateral line position.
Bull trout love smashing these big meaty streamers. Even in small pocket waters and shallow streamers, I’ve seen greedy bulls hit flies like this. If you are planning on an encounter with some bulls, this should be in consideration for inclusion in the fly arsenal.
