The HB Brass Offsets from DMM have a pretty fanatical following and for good reason: their unique shape allows climbers to protect pitches that were otherwise not viable. The units are manufactured from very specific quality brass that is silver soldered onto stainless steel wire. The wires benefit from a color coded alloy swage that is only dinked on one side i.e. one wire runs free so that the head is always loaded optimally. The color coded swage helps with selecting the right size first time.
