My choice is X cams.
Might not be the favorite choice in a hunting bow for some people though.
Nothing is as easy to tune as an X cam.
Sag.
Smart man.
Binary's are cool but honestly I feel nitrous and nitrous X cams are the most verstatile system on the market for hunting to indoors, to 3D, etc. You can change from a traditional cable setup for hunting, to an X system for all target types of archery and eliminate all torque on the system from a cable slide or roller guard.
There are soooo many options with them, much more so than most realize.
