I just got the 7069s which are the flat black version of the 8069s. They are cheap Chinese made but should only cost you about $100 each . I hit a rock really hard (had my rear slide off sideways and nailed the Rimbaud) and it didn't bend or get too damaged. Surprised the hell out of me.
Also got the BFG Km2s . Works great on granite and great on the dirt. Was a night and day difference. Also suprised how comfortable on road they are but I imagine it will change after a few thousand miles. Only thing with them is they run SMALL.
