I purchased Dave Whitlock's video on tying some of his deer hair flies.

For the Diving Frog's legs, the fly requires 3 pairs of neck hackles...One each white, grizzly yellow, and grizzly olive.

I can't seem to find neck hackles in grizzly yellow and grizzly olive...I can find saddle hackles in those colors, though...

Can anyone recommend a supplier for these types of neck hackles?
