In reply to Flicka:
It is good to have a selection, generally I will change which quickdraws I am carrying depending on what the route is like, for example:
- short single pitch (pos crux low down) 4 x 10cm, 6 x 20cm, 2 x 30cm
- long multipitch 2 x 10cm, 8 x 20cm, 6 x 30cm + 60cm slings
- easy mountain multipitch 6 x 20cm, 6 x 30cm + lots of 60cm/120cm slings
