Nub: I think the new Mathews designs would work well with the new Golden Key Mirage drop-away. The Mirage has a small "fulcrum" lever that allows the "pull up" string to be mounted under the rest and utilize the downward motion of the cable. Others use the cable's backward movement which surely wouldn't work on this design.

This downward movement of the cable for activation is another thing I like about the Mirage design. BTW, this could also be designed into other cable-activated drop-away rests.
