I tend to do what you described, but I don't think I've given it a couple hundred miles; maybe 50.
Thanks for the pointer. I might get that Unior tool, I have many tools that i use very rarely (if more than once), so this would fit right in! I'm feeling the late winter urge to start spending bike money. I'm also very glad that you and Unior know that it's a sprocket not a cog.
