Motorcyclist Mag (Jan 2013) puts the Scala G9 above all the competitors it tested for less cable mess, furthest range, best audio, ability to increase volume automatically with ambient noise, 13 hour battery, etc. I know there's a lot of threads on this matter, but I think this determines which one is going to be my value-play.
On a side note - need a quiet helmet. Went to see my parts man and friend (that now manages the local BMW dealership parts department) to purchase a Schuberth C3 today. We got as far as measuring. Didn't have my preferred size/color, but a shipment is due in there within a few days
