In reply to Adam L:
I probably do Our Father once each year and always lower off that dodgy set up. I probably wouldn't do it at all if you had to top it out, as for me, Stoney is a quick evening hit venue in April/May. Maybe stick a lower off in? It would be a very sketchy E5 without thepegs as the rock is brittle in that initial flake, and I suspect you would find it tricky protecting the huuuuge reach into the undercut. I'd go for one bolt and no other fixed gear tho. It's not a good enough route to be worth making it bolder.
As I've said before, I think Stoney is somewhere that would actually benefit from a few more bolts here and there, to replace the iron mongery. If you removed the bolt on Circe, you could feel very clever about leading a poxy, bouldery E5/6, rather than a poxy, bouldery E5. It's a good route to get your head together on at the start of the year. I doubt it is at the top of any aspiring E5 leader's tick list. As the crimp you stretch for on the crux is often dusty/slimey early in the season (i.e. it's an easy one to pop off), I doubt it would get climbed much without the bolt.
There are plenty of routes (e.g. Traffic Jam) that have no fixed gear and should stay that way. Contrary to the Wilson-esque mantra of climbing not turning into a 'convenience' sport, I think Stoney epitomises the convenience crag. It's location and weird perma-dry nature when everything else is wet.
