In reply to coolbert:
So, you are reinventing the E grade so that the E stands for extermination. Why not have a simple scale up to E10
I don't think you can get to the highest grades just by lack of protection, I think you'd need a crux at terminal height, and terrible rock quality as well.
Bolted routes - all E1 unless badly bolted!
Cenotaph Corner E1 5c
Lexicon E4 7a Lots of potential to hurt yourself, but the big fall has been survived.
California arete E7 4c - very bold but some gear and ok rock
Sunset Slab E7 4b Protectionless but good rock, and not high enough to guarantee death.
Brown's Eliminate E6 5b Gear might catch you off the crux, solo after.
Breakaway E9 5b loose deathy shale
