So, you're tall, you've got your right hand in the slopey dish by the lip with your left in the pocket and a heel-toe in the roof/ starting block: question is how do you control the swing?

An answer would be much appreciated (crikey, the number of posts I make wanting to be told how to climb stuff you'd have thought I have no technique and no mates! Oh, right...)

There are two methods for doing MM, and your post has confused me about which hand goes in the pocket in the roof. I'm pretty sure I did it with my left, this being a hard move that stumpies find especially difficult. Thereafter the swing felt okay to me; the mantel did cause a further wobble, but not as hard as the start.
The stumpy method takes the roof pocket with right hand, then a sloper at the lip, and I can't remember the rest, although I have seen Crooky do it this way.

MM is great, but in retrospect, Bombshell is the better problem.

I hope that cheating stone in the break has not been moved back!
