I'm thinking this is a pretty schmick helmet, plus it fits my head. While I'm looking at it and thinking I'll buy it the salesguy comes over and we chat, I tell him I'll be taking the helmet on track and he tells me the current (in store now) GP Pros have a whistle if you turn your head when doing more then about 120 kph. What the...? I appreciated his honesty but am now wondering what to do... really like the helmet but whistling would be crap. Anybody got one of these? Do they indeed... whistle?
