55 year old Fontainbleau local and traverse master Jean-Pierre Bouvier has made the first ascent of Fou fire aller/retour for which he suggests 9A trav.
The left-to-right is an 8B trav. in its own right, while the right-to-left weighs in at a mighty 8C trav. Adding the two makes a 9A...
So if you climb a 9A boulder problem which is a traverse (and so legitimately called a 9A traverse), how would you distinguish it from a traverse problem graded '9A traverse' (also legitimately called a 9A traverse), though actually many grades easier?
I doubt I was the only one who thought this 55 yr old had claimed a 9A ascent.
Well if 8B + 8C = 9A then you could say the addition of an 8C bumps the 8B up by 4 grades, or you could say the addition of an 8B bumps the 8C up by 2 grades...
In reply to Tris: I agree that Font 9A should not be "impossibly difficult". If it was then all the boulders that will be sent in the future that are harder than the current 8C/8C+'s will all be squeezed into the 8C+ grade, making it very broad. Font grades are supposed to be open ended I thought.
