I just read a 6 page interview with KK in the current Power magazine, he does not wear a belt at all when he deadlifts.
Everybody tat is interested in raw strength should read this interview.
Any Bolton is possibly the greatest deadlifter in history though, raw or equipped.
KK wants to lift with AB and BM without a belt though, that would be something to see. KK rates Benedict Magnusson the better of the 2 compared with Andy.
KK deadlifted 215kg@ 72.5kg and 15yo

Konstantins Konstantinovs graces the next cover of POWER! The strongest RAW deadlifter on the planet, KK talks exclusively to POWER about his training, his goals and if he will be coming to the US to compete in the 2011 Andy Bolton Deadlift Challenge. Also in this issue: Donnie Thompson discusses how to “Trick” your body out of pain, Matt Wenning discusses his training philosophy and Dan Harrison talks Strongman. Plus, you can “Get to Know” Karl Gillingham and much more! http://www.thepowermagazine.com/subscribe.html
