To paraphrase him, he describes a "nightmare of a decent, and not one he'd wish too repeat", and goes on to say it was wet and slippy.
No kidding, the decent off a mountain crag in North Wales in February was wet and slippy!
When you are the experienced climber or 'guide', it is your responsibility to ensure your novice partner doesn't have an epic.
It only takes a few minutes on Google to gather all relevant information regarding a route you haven't done before, so in all honesty there's no excuse for an 'experienced' climber to get caught out by this decent.
Personally I've never understood the fuss regarding the decent off the slabs.
Done it many times in all conditions, and taken novice climbers down it too.
My first time in 69', aged 12, as my third ever outing (previous 2 being Windgather and Castle Naze, so first multi-pitch, and first mountain route) with school, as a rope of 3, in drizzle, wearing bendy Hawkins fell boots, Troll waist belt and Viking kernmantle ropes.
No epic whatsoever, because our teacher and guide, a wonderful man called Roy Fisher, was a highly experienced climber who new the terrain like the back of his hand, and made the whole thing a wonderfully enjoyable experience, which was the start of a lifetime of climbing for me.
