Hi Alan
I tie something similar with a hot orange cdc wing that floats and it is very effective. So you have to experiment and try things
this is good.
I add an olive thread and a scarlet red thread to your basic selection for now, and some glo-brite floss in colours 7 and 11 for making cheeks, tails and thoraxes. That would about cover most buzzer combo's you will ever want to tie
