That enduro bag looks about the same size as the expedition small which I got for my adventure. I think it is really well made and you don't need a raincover, which is nice. I just think it gets in the way riding on dirt when you need to get some weight over the front sitting or standing. It is probably the smallest bag out there though, and anything smaller would probably be a waste of time. I like it up as far forward as possible and that means covering the gas cap and taking off the breather hose which is a hassle filling up, but only for a few seconds. Bottom line, I only use it for loaded touring and am just not a tankbag guy, even thought the wolfman is a great bag.
