For nine ounce tanks I've seen the long skinny one like the one in the link as well as a Brass Eagle steel tank (stay away) and I own a short stubby Pure Energy 9oz. The one I own is like a 12oz tank cut short for 9ozs. Pretty nice for people with shorter arms. Looks like the one in the link is what you're looking for. Also, There are 7oz tanks that are even skinnier and lighter.
