david graham wrote a review of Metolius Master Cam on April 20, 2014
These are my favorite cams of mine so far (only have master and camalot C4's). I feel so much more confident when I find a place to use these rather than the camalot C4's (weird I know). Although the action may take a little more force to engage, it is smooth and makes it so the lobes pull back evenly every time. I only wish metolius made larger sizes of the master cams because I would buy those in a heartbeat, but for now I'll keep using these for my small cams. I don't know how these stack up against BD camalot X4's which might be a more appropriate comparison though.
