Wild Country Rockcentric Hexes Set, 3-9 $65 shipped In my opinion the best hexes for rock climbing, these are lightweight, color coded, and the modern dyneema sling keeps the placement from shifting from rope drag. Retail is normally $90!
These are lightweight and a great deal to pick up some rock or mountaineering protection. Much cheaper than cams!
BD #11 nut, WC #8 nut $6 each These are in great shape. Lighter and more secure than a picket when you can reach rock on the sides of a snow climb.
