Sure it's on the pricey side but you shouldn't mind considering you're going to wear a helmet more often because of it and in term protecting your life.
ive used both the ionos, prolight, and whisper plus.
i own the whisper myself, and i will say it's not spectacular by a
long shot - though ventilation is great, weight is somewhat low (i have the 260g european version) and it came in a nifty case. sizing is a bit weird, my head usually measures ~56cm but the medium (54-58) fits only tightened all the way (retention systems pretty good, too). however, if i had to do it again, i wouldn't have paid 200 for mine. retails like, 280 so i'd definitely pass.
the ionos on the other hand weighs a bit more @~340g though ventilation (and comfort) is phenomenal. the newest rocloc system is simple and easy to use (similar to the specialized ones) and in general the helmets great. competitive cyclist was selling them for 120 a few days ago - which is a pretty damn good price. the prolight was 100, though i don't particularly like the rocloc SL system (or maybe i didnt have enough time to get used to it) - though i know a bunch of friends who love it. the straps are stretchy elastic to save weight.
take a look at the aeon too. ventilation (is supposedly) improved over the ionos but still keeping a weight close to the prolight at 230g i think. i havent seen one in person yet.
go to your lbs and try them out for yourself - and you can save the trouble of getting the wrong size!
