Yeah, besides being a bit tight with a pack on the slot felt way safer and easier than the top in those conditions.
In fact I didn't place any gear in the slot. My thoughts were if I fall I'll just make myself 'big' like a threatened pufferfish and jam myself in there.
It was thin to the point of rock climbing. If it hadn't been for the quite amazing slow pace of the party on LH I wouldn't have been on it at all.
