Stan,

Those feathers you mention are not true spade hackles. As you aptly
described, the feathers you mention are pointed. Spades are clearly arched
across the tip. Sort of like the blade end of a spade shovel. Charlie
Collins will tell you that spades, and this is where he plucks his, are
located in the shoulder area of the rooster. I believe he calls it the bow.
If you buy his packs, you'll see that he often just pulls the whole area as
a clump. Regardless, you're right. You'll get a lifetimes supply of a few
colors or shades in each pack.
