What helmet? I've just fitted a Sense ACS-10 to my Arai Quantic. The level of integration is quite impressive, even if the installation instructions are sheeeeeiiite.
Shoei Ex-Zero atm (wind noise is terrible) but tried on a Quantic the other day and VERY comfortable. My wallet needs to recover for a couple of months but will probably align a headset and helmet.
