I've got both an XR1000 and a Rx-7 Corsair....both fabulous and both very comfy.
However, for everyday riding I tend to use my XR1000....suits longer distances. The Rx7 has loads of vents as its a proper race helmet, so as someone says, its noticeably more noisy than other lids. But to be honest, its not like its defeaningly so.
I tend to have my iPod on anyway now for longer distances. Just to stop the madness that is caused by the "hmmmmmmm" you get from the bike/wind etc.
The Rx-7 is lighter and less bulky on the track, but on the road in winds etc does feel a little too light (if that makes sense).
I would defo recommend both, especially the Shoei.
Be aware though, my XR1000 has really bedded in so is now slightly loose, so make sure its fairly tight from the off (I know I know, Granny eggs etc Pat...sorry mate)
Thats my penneth!
