In reply to Dale Turrell:
Personally, I would assume Soudeain Seul is 9A. But that is me, Nico Pelorson thought 8C+. Alphane is 9A (soft) in Wills eyes.
I would have thought, it just takes a couple more ascents and the grade of Soudain is more solid, likewise in Alphane. Or is that thinking too conservative?
While your argument is interesting, it only builds on one opinion, that of Simon Lorenzi. OK he is the only one that climbed both. So we could deal with more opinions.
