Probably won't be too much of a problem. When I led the route last year I used the 2 finger pocket. It didn't cut or cause any problem for my fingers.
I chose to use it as that sequence looked like it would flow really well for me. It did! Not sure 100% if my sequence eliminated that larger undercling ..... I may have still used it briefly?? The way I did it using the 2 finger pocket it was still only 23.
I know Steve didn't use it when he led it ...... but we rarely climb the crux of any route the same way! Great route.
