Gals here recommended the Giro Havoc when I crashed and needed to replace a road Giro. I got one and loved it (really like the visor, even for road riding, as it turns out - helps keep the sun outta my light-sensitive eyes). I just crashed yet again and bashed the side in - arrggh! I only got wear it about 3-4 times! So, I've just ordered two more (cheaper shipping) off eBay. They are 2005 models but just fine, brand new, and half the price of 2007 models. Now I'll never be without a backup! Anyway, you might want to try the Havoc on for size. REI carries them as well as LBS's.
