I have often noticed that the trout prefer these red colored Spent Mayfly spinners. At least when the Aurvilli hatches have been going on for a while.
Hook : Ahrex FW502 Dry Fly Light #12-14
Tying Thread : Semperfli Classic Waxed thread 18/0, Red
Tail : Fibetts, Light Brown (4 pcs)
Body : Stripped Peacock Quill, Crimson
Wing : Sparkle Organza, White
Thorax : Hares Blend Dubbing, Red
By changing the stripped peacock quill with dubbing, you will easily get a fly thats float higher, by impregnating it. But it is not a big problem with these quills as well, the fly will float long enough, and you shake of the water when throwing out in the river again.
