I'm now facing the same dilemer after damaging my onza carbon bars. Damage don't look too bad but I'm still worried. Theres a scuff where the onza logo is. Although it doesn't look like it has gone past the laqure this going to affect them much? what did you do in the end with yours replace them? Also where the bike has been dropped numerous times the ends of the bars have a few chips and cracks in. i thought the fact that my grips had rubber ends on them would protect them. Apparently not this going to effect the strenght too?
