This is a really interesting thread for me. I have 3 full 'capes' and another chinese partial hen section (by the looks of it) that came in a pack when I started tying again.
Two of the capes, my Grizzle and my Red/Brown - from different sources - are great as far as they go but they are very similar in feather size and are really hard to get an exact match on some size flies. The grizzle being on the short size and good for smallish hackles/cranefly wings and the brown being a little long in most cases for the smallish flies I tie.
The other cape is awesome it's a Black Keough Genetic 'Tyer's Grade' cape (whatever that means) and it has really strong hackles in a great variety of sizes. I actually bent a hook when I tried to rip the hackle off rather than trim it the other day
I'm guessing that the first two are saddles and the latter one is a neck cape but my, what a difference it's a wonderful asset and I wish that I had many more colours with this versatility but man, it was £40
