Just been discussing this with Pantontino - 7c+/8a does seem the consensus grade I guess. As Doylo says, if the knee bar fits, wear it! I would still say 8a though, but maybe it does'nt suit me. I think that Halfway House and Directors Cut would maintain the grades they have been given, even with new beta, as Trigger Cut feels alot harder after 10 plus moves into it. You could argue with that and say ' thats not how it works on paper' (I've just done that!), but thenmaybe that its the physicality of the problem, not how you do the sums, that set the grades in stone (until new faggotry comes along!)... ???
