In reply to mike lawrence?:
Maybe I'm completely biased, but I would say that much though I love the Upper Tier E5s none of them are a patch on any of the ones down at Main Cliff - they're good, but kind of missing the point.
Furthermore, all of the E5s on Main Cliff are comparatively well protected. Ordinarily I carry a couple of sets of cams, it's a bit on the heavy side to begin with but usually you've unleashed half a rack of them into the crag by the half way point anyway!
Whichever you do settle for, you won't be disappointed!

p.s. if you do end up on Dinosaur leave it until late in the day, early on it suffers badly from the greasy conditions.
