In reply to Billg:
It's times like this when I wish I had a better memory....
I did New Dimensions a few years ago, but can't for the life of me remember whether it had new bolts in or not. Part of me thinks it did, but that the old ones were in there too (I have recollections of rust...) - hence you could clip quite a lot of things both old and new. What makes me inclined to think the new ones WERE in is that I don't remember being terrified by old gear. This is the sort of thing I would have remembered and commented on within my logbook. If that isn't the least helpful advice I have ever given I don't know what is*
On a more helpful note, I would highly recommend doing it in a single pitch, all the way up to the 'Mini-Finish'. It requires a bit of skill + ropework, but pays dividends in the long run as it is a truly unforgettable pitch...apart from the bit you're asking about...which I've definitely forgotten...
Certainly up there with the best E4s Wales has to offer.
* I'm almost certain I've given Duncan (Campbell) worse advice previously, but in keeping with the recollections above can't remember exactly what that advice would have been...
