[VFB] re: hackle winding question

[Joyce's crafts and flies]

I'm tying Moseley Mayflies, which, as you know from the previous discussion, 
are tied with three hackles wound dry fly style. Now, here's the question, 
in your experience, tying them as Hans W. does, by tying in the hackle at 
the hook eye and winding backwards, then winding the thread through them, 
how do you find it best to do with best results..one at a time and tie down 
or all three together or two then the yellow one wound through them. 
Inquiring minds would really like to know what has worked best in your 
experience. Thanks for your imput. Joyce
