It's a level playing field though. All helmets are tested on the same basis and all could be modified to fare well in the test if the manufacturers could be arsed. That some apparently choose not to modify their helmets in order to increase protection in vulnerable areas worries me, and as a result of this and many other considerations I will generally steer clear of any helmet that achieves fewer than 4 stars... so that's most of the "poser" ranges out then The test areas were not chosen at random by the way. The reasoning behind testing the side of the helmet seems to me to be quite sound.... This next quote is interesting as it seems to conflict with what you have been told about the little bit of padding added in a specific area to affect the outcome of the test. Maybe the information related to you is slightly wrong as it seems that the test will not allow "helmet optimisation" to affect the outcome? http://sharp.direct.gov.uk/about-sharp/ In answer to your question, in terms of safety alone, I would choose the helmet with the 5 star rating. If you factor in other considerations such as comfort, noise reduction, venting system, visor availability, pose value and price, then my decision may well be different. What I would not do however, is choose a helmet on the basis that it says "Arai" and costs in excess of £300 so therefore must be good.
