Thanks guys.  It took me a lot of iterations to come up with that.  I went from a realistic looking bull, to a cartoonish bull, to a more artistic bull ala my avatar, but I settled on something iconic in nature.
As for the helmets, maybe (with Brad's approval of course) they could be used as the helmet stickers.. ÂÂ
Helmet stickers would be great I would love to put them on my BULL horned helment
