3 pebble slad at Froggatt in the Peak District. On top rope, or second, it's about HS, or VS climbing, but on lead it's E1, cos you wi8ll deck out for about a quarter of the climb (the top of a nice slab, so not too hard!).
It's probably the easiest E1 you can do, and doens't really deserve the grade, unless you don't like exposure. I don't mind it, as long as I can't really see it!
Incidentally I have seconded Strapiombante (Froggatt), Safety Net (Roaches), and about 2 or 3 other E1's, which have all inclded hard moves, but not immensely hard climbing (Strapiombante is quite hard), but I seconded Long Tall Sally (Burbage North), for a Danish looking gentleman this morning, and that was seriously hard climbing all the way. It had to be E2 for me though because he fused his Rocks to the crack.
If anyone is interested in Long Tall Sally, then can I laugh at you?! It's ridiculously hard for an E1!, but he did place the gear where I would have wanted to place my fingers. It's a good finger crack, but it's pretty hard. Oh and it's better protected (esp at the crux), then it looks from the floor!
