I was on that exact route (Parsley Fern Gully Left Hand) a week or so before the guy with the helmet cam. It was in worse nick and we couldn't stand up in the wind when we topped out! Moved together with my partner until the exact point he fell off 'cos there was no gear anyway (so it was perfectly reasonable for him to be soloing up to there). I did think it got surprisingly awkward at that point for a Grade II but you can never tell in winter depending on conditions.
To be honest, with a 17 month old daughter I've been thinking of knocking the winter game on the head and watching that having just been on it is only cementing the idea in my head!
