In reply to HeMa:
> Interesting... some of the stuff I've climbed here in Finland (as has Toby) seems quite stiff then... Because the stuff seems to be around M4+ and indeed felt like Tech 7 (Para Andy, Piggotts and Cutlass). Perhaps, it's too stiff here. But then again, some of the stuff has also been climbed by people who've climbed mixed stuff in Rjukan, and also in the Alps. So they do have an idea with M5, M6 and so on feels. Perhaps Piggots and Cutlass are egoboosters when it comes the the tech grade.
M5 in Chamonix is like tricky tech 6 or easy 7. Pelissier gully, vent du dragon, Rebuffat Terray (might sneak low tech 7).
Goulotte Pepite gets m4 - it's got one short step of tech 6.
Madness Tres Mince M4+ I'd say tech 6+ in the condition we found it but I could imagine it being easier.
Generally alpine M routes are fairly well protected so the adjective grade would be matched, or one below if the crux is short.
In the higher grades it seems like (currently) there is a bit of compression of the M grades - but many feel that M7 and M8 routes are highly overgraded as there are basically no M6 routes around.
Maybe linearity shouldn't be assumed?
