The use of helmets is one of the most controversial subjects in the forums. Add to that the fact that helmet use spans all types of bicycling, from Road to Mountain to Singlespeed to Vintage to This and to That, if pro-or-con helmet discussions were allowed in other places the entire forum would explode. Helmet threads are allowed elsewhere if they are objective fit or style threads, or how/where to purchase, etc. The reason why this thread lives (along with its predecessors) is because Cyclists are passionate, and are not afraid to "share" their beliefs. The question you had, about a particular model, would probably work better in the Road forum, although moderators would watch it closely to make sure it didn't escalate.
