mike adams climbed "adults only" from the rightand side. basically start on righthand side of arete (codiderabbly lower than adults only because of the boulder) slap up arete with lefthand until you can make a wild cartweel move the break with the right hand. swing round and finish up adults only.
mike reckoned about 7c for this quality bit of climbing. how ever he was able to reach the sloping ramp for foot on AO, with this for your lefthand its a considerably harder move, at least one grade i would say.
the problem was dubbed "delusions of grandeur"
