This somewhat obscure problem is worth the effort to find. Undercling the big coffin-shaped hueco and make a long reach to a jug, apply some neat foot tricks to move to the rail on the lip, then get your feet up without dabbing and top out. The holds at the top can be a bit mossy from lack of traffic, but it's nothing a brush can't fix. A true hidden gem.
(There is no "official" grade for this problem, mine is only an estimate.)
On the left side of the roof, starting on the obvious large coffin-shaped hueco.
A pad and a spotter to keep you from rolling down the hill, should things go totally awry.
