Ok, I did this a while back, but ever since there has been debate as to what's in and what's out.
My method was to pull on use the sloper on the right, pull through to the small sloper up and left then delicately pull through for the slopey top-out.
Everyone else I know who's done it used the groove as a foothold.
My thoughts were this would be a slightly harder variation on the groove, but not be worth mentioning as a separate problem.
I'm not interested in what grades the different problems are , just what the original, or usual method of ascent is and which line the problem takes.
cheers
