If the rock's anything like Booroomba (which I believe it is) you clearly need a rack of wires and a stack of cams. And as Monty says, big ones are often useful on granite. I also like to have brass wires and slung hexes. Not necessarily on all routes, but near by.
But MUST have, I guess just cams and wires. And extendable draws. But anyone climbing trad who doesn't have those already needs their head examined. |
