I would highly recommend a partridge skin and a starling skin. If you shoot, you can get the starling yourself. It's a very good skin for soft-hackles, and highly under-rated. Don't make that mistake. One of my most productive soft-hackle patterns is Pritt's Water Cricket in size 14 (yellow body with black thread as a rib, starling hackle, and black head; you can do the body in orange as well, also good). A black bodied fly, size 16, with the hackle palmered half way down the body is also a very good pattern (Stewart's Black Spider is it's name as it was first published in Stewart's book in the 1800's, but he credits the fly to a fellow by the name of Baillie's (sp?), so some call it Baillie's Black Spider. Pritt also suggests something called a "Little Black", which is similar, but has a purple body).
There are good usable feathers at the "elbow" of the wings of ducks and pheasants (cocks and hen birds both), and others along the wing. If you have a male golden pheasant wing, the chestnut brown wing feathers are similar to woodcock and can be used as a substitute (though if you really get into soft hackles, you'll want a woodcock skin, moorhen, and snipe as well - ok, like most things fly tying, you'll want everything! )
