The other crack on the same arch was successfully linked with a face climb above, and to the summit (Southern Belle).
That crack was FAed separately by someone else, then came the FA of the whole route, and finaly the FFA.
It was bad judgement on the part of the GU team to think that lightning would strike twice - and the westerly crack would just magically transition to face moves, and summit glory.
The simple fact that DR stepped back from his association with the route, his footage and or writing(?) of it speaks volumes.
