In reply to Sian: Ok Ive only done 3 E1s and still look for the 'soft touch' ones so I'll tell you what I found.
Long Tall Sally (Burbage) - My first one and probably the hardest. The gear after the crux is hard to place on almost non-existent footholds so I ended up skipping it and running it out to the top which was scary to say the least. Great climb but probably not such a good intro to the grade (why do so many people end up on this as their first?)
Kirkus Corner (stanage popular) - Hard but enjoyable moves past the only decent gear puts you on a ledge with a fairly simple slab above you but the prospect of a very nasty fall if you mess it up.
Billingsgate (Millstone) - my favorite one so far. thin technical climbing but on very good gear (providing you have two or three no.1 nuts and a very small cam) not very long, probably one of the shortest routes at millstone but very enjoyable if you like the odd two finger crimp.
And maybe after that try...
Crossover E2 5c(Stanage Plantation) - make sure you have rigged it up so the belayer can run back if you fall from the crux and go for it. (quite scary)
BUT I do agree with most of the others on here that a few more HVS would stand you in good stead. Not least because there are HVS climbs much harder than any of the above. A few to choose from -
Flying Buttress Direct (stanage popular) - Absolute must do climb, brilliant hard but well protected crux (once you work out how to place the gear)
Great North Road (millstone) - it just keeps coming with committing, hard moves but on good gear
Lyon's Corner House and Direct variation (millstone) - Both great climbs on good gear with sustained interest.
The Sloth (The Roaches) - I still havent had a chance to try this but my god it looks imposing.
Good luck!
