In reply to JJL:
Yes, we made a mess of finding the start as well. The sign in the RF guide has fallen off the tree but you still won't miss it as it was balanced on a rock, or something, next to the path from memory. You'll be following red dots up to this point but the secret is to STOP following these once you reach the sign. We didn't do this and having followed the sign right we then mistakedly looped back left towards the red dots. We lost around an hour in the process following them up some creek.
The descent back in the direction of the South face car park didn't look that bad btw, although we didn't have enough daylight left. The RF descent description suggests an epic will ensue but the photo showing the line of descent is pretty clear so I really don't think it would have been a problem. I would do a route on the East Face to familiarise yourself with the summit area first if you have time.
I think one day for the ascent is ok provided you can move quickly on the easier pitches on granite slab, are largely happy using the bolts in place (sometimes a little sparce), and are happy moving together on the easier pitches. Most of the climbing is in the lower half so moving together through the easier upper sections is critical. Bring a light rack to supplement the bolts but be prepared not to waste to much time placing.
