Those H&H capes are 3rd level quality. Not a bad thing, but if your asking are they good quality dry hackles? Many will probably say "not really". However if you looking to practice, it's hard to justify spending 3 or 4 time as much for high quality hackle.

J Stockard has a wide range of hackle available in all quality levels and prices ranged.

Whiting 100-packs at Cabela's (and other retailers as well). enough feathers to tie 100 flies in the same same size. The good thing here is, if you are ONLY looking for a given range, you wont still have a 90% unused cape in 10 years.This marketing idea, is only buy what you need perhaps?

Mini packs at Bass Pro for $5.99, 5 different colors each containing sizes 12 to 14. Buy all 5 for what 2 of those H&H capes cost.
