I climbed all summer on just nuts, hexes, and tricams. I climbed Culberts Route on Mt. Colonel Foster on Vancouver Island with all passive (5.8 1100m). The rock there is terrible for pro but tricams worked alright in places. I love the small sizes of tricams. They work great. I fell 15 ft onto the pink one when I was in Ireland on a E2 5C (about 5.10d) crack. It held fine. They place alot faster than hexes too. I just got a set of DMM 4cus and found they are quite a bit more convenient, but the tricams are nice as your second set of cams in the small sizes. That way you just have to double up in the bigger sizes.
