We discussed a lot of climbing issues such as double vs Single vs twin ropes for routes, Safety of climbers on stance. Efficient changeover at belays, stance can accommodate everybody/organised such that the leader can move off with the minimum of fuss and disruption, leader and second stacked in climbing order (e.g. leader at top/outside; second at bottom/inside), leader on stance at side they will move off from for next pitch. Leader/second clipped in without crossing ropes Sort ropes out so leaders rope on top of stack (back coiled). Tying into anchors (single and multiple): linking anchors with sling Vs tying into anchors, clipping ropes and extending runners. Belay direct and in direct. Abseiling from rock anchors, backing up anchor for first person down. Cows tail on harness for clipping into belay, the use of friction devices and the use of the French Prussic.
What a day!
