/ mixed vs winter grading
I am not sure they can with any meaning.
I wouldn't bother trying to convert as you will get depressed. Doing laps on D7s at white goods won't make you happy when you back off fallout corner at m4 or when you realise that die reisenwand on Beinn Bhan is actually only m3.
Isn't the Indian Face supposed to be F7c? Makes it sounds easy doesn't it..
By the way, I totally made up those m grades off the top of my head.
Quoted from the Rockfax Rjukan guide:
M4 = Scottish tech 5/6
M5 = Scottish tech 6/7
...and so on.
Basically add 1.5 grades to the M grade for a rough Scottish tech grade.
You wouldnt expect to be doing fig 4's on M6 solar for instance, but on a modern quarry M(D) 6 you probably might....
You'd have to be doing some crazy stuff to fig 4 on M/D6.
