In reply to Monk and many others: I'm now going to do my "grumpy old man" bit - those routes are never E1, don't know why they've been upgraded, load of wall-bred softies, blah, blah, blah.
For people's historical information, here are some of the mentioned Peak routes that have been upgraded since they first appeared in a definitive guide with technical grades in late 70s, early 80s (obviously if you go enough guidebooks back then you'll find some that used to be VS)...
Strapiombante - used to be HVS 5b
Pegasus Rib - used to be HVS 5a
TPS - still is HVS 5a
Debauchery - used to be HVS 5a,5b
Cent - I'm sure this was VS 5b at one stage - may be wrong.
Louie Groove - used to be HVS 5a I think, however this is one of the few where the holds might actually have changed.
St Peter - used to be HVS 5a, presumably it's even more polished now
By the way Minus Ten is classic VS jamming - none of this HVS stuff. Well protected unless you're copying what young James appeared to do in just going for it and then taking a spectacular lob - any photos?
Of course in reality, like most of you who operate near the HVS/E1 divide, I too happily grab any upgrades to E1; I always reckon that I become a better climber every time a new guide comes out
