Though I made an exception for my new Scorpion helmet (only because I got it as a package deal with my new Scorpion jacket), I generally ONLY buy ECE certified helmets. In the past that pretty much limited me to just Shark, but with the new nonsense going on involving Snell, many other brands are switching to ECE. Scorpion is replacing the EXO 400 and EXO 700 with the 450 and 750 (though its a slow, phasing out process), which are identical but now have whats called World Standard certification, meaning they are DOT and ECE certified and give Snell the middle finger. All Icon helmets being made from mid 2009 on are the same, they’re ditching the Snell certification for the ECE certification.
The recent motorcyclist article that they did as a followup to that one you linked was basically Snell admitting (though not in so many words) that ECE was a better test and that they are changing their tests so that they somewhat mirror ECE. By doing this, Snell has basically made it hard for the helmer manufacturers to take them seriously, and so the Snell certification isn’t as important as it once was. In fact, many are saying that it is more important to get ECE certified than Snell.
