With the most versatile offering of cams on the planet, Ultralight Power Cams, TCU's, Fat Cams and Supercams, why add a single cam to the Metolius line? The reason is that there is an infinite number of variables in the climbing envrionment: hard rock, soft rock, parallel cracks, flared cracks, etc... Each individual cam style excels at a certain set of variables. The Fat Cam;s wide lobes greatly improve protection in soft rock while the TCU's narrow head widths greatly enhance placement versatility. The biggest advantages of the single-stem unit are: they will fit into certain placements better than the U-shaped body and the flexible, single cable reduces leverage to minimize walking in certain placements. Metolius set out to make the finest single-stem unit they possible could and the Master Cam is the result.
