Back2back walk away

This is nothing more than repeated back to back rolls in a plane breaking position in front of you. I use the three finger cradle for this one, because it gives more control. The ball is transferred smoothly from hand to hand, there should be no jarring motion at all. This can either be done as an isolation as shown in the clip, or as a true "walk away" where the ball leads and you follow.
