"American Cowboy Billiards" is the eBay store, but they've been sold out for about a year. I personally love the stuff. It's not as smooth spreading as Master or Triangle, so you have to be a little more careful in chalking, but I think it works its way into the leather better and deeper. Miscues for me are non-existant, and I often don't chalk for every shot when I'm in the middle of a nice run. It doesn't stick well to phenolic or composite tips, because I think it has less binder in the mix than most other chalks. I don't have enough to sell, but I definitely would give it a try if you can buy some reasonable. JMO
