Of the four samples, the consensus is that the Coyote is the softest. I happen to like the American Eskimo, and from the fur I have been saving I know it is going to be great!
How much have I saved? When I weighed my collection in early February, I had 4 g of fur. Sure, this seems like not very much fur for 6 months of ownership, but Indy is starting to shed a lot more. He is also much more amenable to long brushing sessions.
