The India hen feathers are typically too large for trout sized flies, and the I've never like the barbule structure of Indian hen (too wide/blunt, granted just a matter of taste). Much prefer genetic hen cape, but you are right those Whiting hen capes are now ridiculously priced (is anyone buying these any more?) and the Clearwater stuff is no better. Spencer Hackle used to be reasonably price, but with Hugh out of the game now, Collins is probably your best shot.

Of course, another way of looking at it is consider the price of a partridge cape versus the price of a good genetic hen cape. I'd argue the hen comes out more economical anyway you look at it.
