"add 2 'biners for a mountaineering quickdraw etc." - Review of Black Diamond Nylon Sewn Runners
In the mountains you won't necessarily know how far off your line the next anchor will be. Use runners with 2 carabiners as your quickdraws. Double or triple the 60cms on your rack, open em to get about 10, 15, or 30cm of reach, and be able to sling a chickenhead etc.. These are versatile, and cheap enough to leave one at the anchor. In a pinch you can cut a 60 and loop a tree with a water knot. A 60 makes a good shoulder sling, two 60s can make a shoulder harness, etc.. Buy a bunch.
Pair them with simple wire-gate oval carabiners for the most versatility year 'round.
