In reply to featuresforfeet:
The gear is probably OK, but falling off is a bad idea given that for most of the route you are in a chimney/cave and thus guaranteed to swing and hit something if you slip on wet rock. Pitch 2 can be very wet and slimy, as can the lower half of Pitch 3 (all of it if it's been wet recently).
First pitch is a steep but positive traverse; I don't recall any issues with gear, but it was quite tiring.
Second pitch was a bit of a 'mare. It's very three-dimensional climbing (you have to be looking for gear and holds all around you): you bridge into the cave some way then climb up in the dark to a boulder-choke ledge and get runners in (I found 2 cams here, left on the ledge in the dark). Rope drag can be a problem as your partner may be belayed some way out towards the cave entrance. Then there is a fairly unpleasant section of greasy/dirty/slopey-holds rock to overcome (the crux), with small uncertain wire placements and your ropes going in some odd directions, until a traverse up and left past a jammed piece of ammunition lands you on a ledge under the skylight. A head torch would have helped, but that would surely have counted as aid....
Pitch 3 feels like it should be a cruise, but actually has a reasonably hard move on it (maybe 5a but dark and wet, so I think it gets 5b), at the overlap. IIRC there should be bomber gear (hexes I think) and a hidden hold that make it OK. It keeps going right to the top though.
I'd say that the grade is a good compromise on a very difficult call. If nothing else, it's a suitable warning.
