I don't know enough about the history of this problem to say exactly how it is to be done. But left of the crack is a good right hand edge and a left hand undercling. If you can pull on from these, throw to the good downsloping 10 finger edge at about 8 feet. Then without using the crack, muckle or mantle over. If starting this way is breaking your heart, use the right hold and give the ol' heave ho from the ground to gain the 8 foot edge with your left hand and go from there, it will probably offer you a more equal challenge for the grade.

Perfect landing under a small venture, but a pad is nice.
Nice job Andy. This problem is actually called Left Bulge. It was originally done via a cheatstone in 1967 by Pat Ament. It appears it was repeated that way until CG and Harrison Dekker added the low start in the early to mid 1980s. Benningfield mentions the low start to the problem as if that is the problem. Not at V5 it's not.
Three versions (grades are just estimates - form your own opinions!): High-start from lip (cheatstone or jump) ... V4/5 Regular-start with LH undercling and RH crimp ... V6/7 Low-start (very tricky, funky and powerful) on double undercling ... V? (Marcelo Montalva did this/repeated this in early 2006)
A short, but fun and challenging little problem. It's almost always fun to go where Ament and Gill did.
The low start seems very hard. V9 or so. The Benningfield guide is full of similar descriptions and looking back was clearly written for a small crew of insiders. How times have changed....
Finally linked the low start--seems solid for V9 with many tries. The real crux wound up being the reach to the lip, a move I blew half a dozen times at least.
