I can't talk about Conranch. I can talk about Whiting 100 packs, necks, and saddles. I love the Whiting ( not Hebert Minor Hoffman yada yada yada ) for small dry flies (16 to 24). I don't like the color of the dun, but the fish don't seem to care. The 100s are great, VERY easy to tie with, no twisting, small stems, dense hackle. As Charlie will attest, I've bought a lot, and will buy more. For the tying I do, it's the ultimate. For 16 and larger, other brands seem to work just fine. Metz had quite a problem with twisting, but things have been better of late I think. I know Denny has some very interesting colorations, Cree, etc. It depends on what you're tying.
