It is just left of the undercut flakes. It uses the tiny undercuts then use feet(polished)on smears to make a quick slap up n right into groove(hard to hold)onto like a boss/pinch/sloper thingy(powerfull),then slap agin with either hand to ledge.
Is hard but not 8a. 7c/7c+ i think . Jonny dawes pproblem i think so shortys can still do it.
Hope this is of use,
