kevin dotywrote a review of Metolius Ultralight Master Cam on July 15, 2019
Familiarity: I've put it through the wringer
The Metolious Ultra cams are a must. It is common to have a rack with doubles of all Black Diamond Camalots. However, I know like to climb with at least a few Metolius Ultralights on one side of my harness instead of doubles in the .4-.75 range( it all depends on the route). The reason is that the sizes are in between the BD sizes so you have a better chance at having the right piece for the crack. Having a variety of gear on your harness is a bit overwhelming at first but I find it the best method for onsite climbing. If you were to buy just one of these I would say grab the Orange #3 for in between .5 and .75 BD sizes.
