I was using the obvious smear with LF and trying to avoid the barndoor by toeing down on small edges out right.
Does the best sequence for lay-by arete involve a RF toe-hook move under one of the flakes out on the RHS ? Sort of dynamically catching it as the RH leaves for a higher side-pull/flake (LH and LH on arete)?
when the time comes to transfer from the RHS to FRONT ON you can slap your RH with your thumb pointing down to stop the swing, and then you can really stand on that left foot.
