Seems like Harf isn't trying to land a clean 12 anymore. Smeele and Rusty both said they were trying them. Rathy said he was trying them Hs Bs. Bob Soven looks like he might be trying one in http://vimeo.com/8445836
I think landing a 12 on my heel edge would be way easier than landing a 10 blind on my toes. Why haven't we seen another 12 in almost a year and a half?
