I don't know why I just feel more strong and more comfortable raising my butt higher. I wouldn't call it SLeg deadlift (yet). My torso would be around 20 at most 30 degree(maybe less) to parallel when starting the pull.
I don't have clip right now.
I find emulating lamar gant the best with his overly exagerated outward feet position. It makes us explosively jump, ala olympic pull, on conventional deadlifts. But it takes awhile to get how one balances in executing the lift.
