Luckily we threw in a few small wires before starting as used on pitch 1. We took a #4 and used it , but often more as a game as to where to place it as early as possible, and it wasnt essential.
Otherwise we had about 1 1/2 sets of wires (including some offsets) and double cams to #3 as the pitches are quite long and about 7 bolt plates needed. I used quite a few small cams on Pitch 3. The good thing was that if you sized up the pitch and didnt want to carry some gear you could always stash it in the small haul bag which we used as we trailed the second rope.
