It seems like all of the futuristic projects (V15+) we see are on overhung, cave-like features. This makes sense because being overhung automatically adds difficulty since you are working against gravity, but it seems like there should be boulders out there which are not overhung, but still sufficiently technical to achieve a high rating.
Not a boulder, but I'm thinking specifically of the "Changing Corners" pitch on The Nose, which is a featureless inward dihedral whose sheer difficulty comes from having nothing at all to work with -- quite the challenge for not being overhung!
Are these boulders simply overlooked by people looking to send something futuristic? Is there a cap at which you must go overhung to progress the grade? Why?
