I haven't done that route for so long I think I forgot it existed. So I have no opinion.
On Karate, I think that is better left as is. It makes you think, especially as a leader, about protecting for the follower. There are precious few of this kind of route over there (Culls in space too), I'd be for leaving it as theres the history of the thing as well, despite the fact that it's a real strange hit follow.
There are plenty of straight up routes over there, no need to straighten this one out - my opinion only.
But as Kev says, it IS Smith after all:-)
i completely agree here. karate crack should stay as is. it's also is the best spot to belay when doing the chimney above.
sundown also has this same style anchor setup too
