There are two lines to the left of Andy's route, one which has been done, and one which to my knowledge has not.
The one that's been done is to the far left and gains a painful pocket with the right hand followed by a big rock over to the lip, this one is on the list, I think it was done quite a while ago and is 7b+ or 7c if memory serves, and harder than it looks.
The line that i don't think has been done is between this and Andy's route, following the features curving to the right. Seem to remember someone saying that Bransby had climbed most of this, but not finished it off. This line is generally even more green and minging than Andy's route. Had some goes on this, but it's not as good as it looks becauseafter the start you can reach holds on Andy's Route.
