A pro-strongman that I've trained with several times Mark Keshishian (sp?) he lives about an hour away invented his own style to "clean" the axle at "the beaty and the beast" contest in 2000, he did a mixed
grip pull and caught it in the crook of only one-arm to get it to the shoulders, "the Keshishian" is the name of the clean, several men along with Mark Philipi used this same style at the "arnold" strongman event this year.
I still don't see how or why they don't try to striaght clean it, or use a strong continental clean, maybe they do, it is some big weights, but these are big guys so I think it's doable.
