HB offset brassies at yosemite gifts or at the yosemite climb shop, they ship fast. Aluminum DMM (HB formerly) at the same places, been using them since I got them when they first hit the shops. Stick well in sandstone and granite, no complaints. Had a set of HB's before I lost my gear in a fire, think their about the same. Believe their distributed by Excalibur in Salt Lake.
