Forgot to add .
Mick Fowler was once saved by his rucksack attached lanyards to get a sneeky rest on an FA in glencoe.
However, have a plan. I was almost caught out once , using the no rucksack, bandolier method. Pumped stupid on an overhanging crack , one axe was hooked above my head , but I had no strength left to pull up or unhook it. I tried to slip out of the bandolier to fall off but it caught up on my helmet.
Very nasty hanging from the helmet strap until I managed to free it off .
I now link the bandolier to my harness.
Even if soloing , a harness is always nice to wear to keep all your clothes snug especially if there is an updraft.
