Hi Grahame, I much prefer Hen Pheasant tail for Invicta wings. The shape and low profile just looks better to me than paired Hen Pheasant secondaries. I also like to tied a long-shank version of this fly right up to size 6 to match the size of the natural fry, so Hen Peasant tail is long enough to cope with the larger sizes.
Worth spending time (and money) on finding the best quality Pheasant tail feathers. There is some very poor quality feathers on the market so make sure you invest in the best, it makes tying the wings so much easier.
