I´ve got beta on how not to do it
It´s way too hard for me.
The first method that was tried was to lieback the crack, then traverse the very slopery shelf to the left until you could reach the standing starts right hand crimp. From there it is "possible" to somehow get the left hand to the arete.
Some new method was found this spring that made the problem possible. I think that you must climb a little higher from the crack. There are some small edges that can be used to do the traverse left slightly above the shelf. Some weird foot work may be necessary.
The standing start seems to get full 8a on this side of the pond.
