Well after 3 years of riding with Sidi SRS, I picked up some SG 10s. Haven't rode with them yet, (I'll do that tomorrow), but just by the looks it doesn't look like they will chew up the airbox as bad (Since they have a nice placement of rubber where the boot meets the bike, hope the rubber hold up and is replacable though). And since they don't have a adjustable calves I won't have to worry about loosing the dang calf screws, and washers like I did in the Sidi. Those where the only things holding me back from buying another pair of Sidi, I got tired of messing with lost screws, or ripped out screws in the calf area. Well I better get to bed, so I can go rip around in these shiny white suckers in the morning,
