i have a smith holt. its the only helmet ive owned. i tried on a lot of helmets though all of which weren't to comfortable though. i ordered online without trying it on (dumb i know). i took the chances but im very pleased with the outcome. best fitting helmet for my head thus far. looks sick and got it cheap on SaC.
but yea, i suggest you dont do what i do, go to a shop and try then all on.
