If this moutain is a snow & ice job, I would take the CS and a leatherman. Why? Because the CS is strong enough to chop steps in ice if I loose my ice axe and the Leatherman because its a good tool.
If it's below the treeline, I would loose the Becker. Keep the rest but distribute them about my person so that I always have a knife on me. The CS can go in the pack.
