If you don't want to honor you commitment DH, that is fine. While I'll miss the ability to have fun with you, mainly your loss not ours as we are having fun, and not really all that concerned about winning.
Oh, and I suggest you not sign up for Wild Geese duty in the future, as it really ask that you give up a certain amount of freedom. Don't get me wrong, I know you do like to fly for the underdog, but only on your own terms. Being a Wild Goose means doing so on terms other than your own.
