i've got the Bern Watts. Serious lack of ventilation. My next helmet will be the Bern Macon, more ventilation. If i don't like that, i'll get a road helmet. I generally don't like road helmets, mainly because they make me feel like someone who likes bikes too much and spends all of their time on bike forums.

Also, if you're looking to get a helmet - www.ccs.com. I got my Watts for $40 as compared to $60 everywhere else. great deals on the "urban" helmets.
