you shouldavoid using the "CAMO" string for your loop. For some reason it is a smaller diameter cord and will slip through the jaws of some caliper releases.
Only if you use camo loop material with a diametersmall enough to slip through the release.
Brownell camo loop material with a diameter of .078" or .083"is plenty large enough and larger than many other materials. Brownell also makes a "low creep" material that measures .068" in diameter is is the best IMO. Very slick, incredibly wear resistant, and light weight.
There are many many different "cords" made from many different materials available to use a loop material.
AS to the original question just about any release made from any of the major players in the release business will work just fine. I have a Scott sabertooth (dual caliper)and it is the bestI have used to date. It is part of the new "family" of releases from Scott which include thesilverhorn (hook)and the wildcat (single cliper).
