Thanks Snowolf. I'm familiar with most of these drills, but it was a good refresher, as I've stopped using some of those drills for some reason. The leapers are one I haven't played with much, so I'm looking forward to giving those a go.
I love the pivot slips, we do a version called picture box turns where we don't actually change edges but steer the nose down into the fall line, bring the board back across the fall line, then steer the tail down, all the while keeping our upper body faced down the fall line. The picture box part comes from creating a "frame" with our hands, stretching them out in front of us and putting an object inside that is directly down the fall line. as we pivot the board underneath us, we try to keep the object in our frame - if you get upper body movement, you lose the object. You've probably used that one.
We also do a pretty cool little static drill I'll offer up in return - it may not be new to y'all, but I just learned it. Pair up two people. Have one with their board on, one off. Person with board is on their heel edge, person without stands in front of them with one foot jammed up underneath the other person's board. The person with their board on then twists the front of the board down toward the toe edge, starting with the front foot, until the board meets the snow and begins to turn, then follows with the back foot to bring the back of the board around. Great for really showing how the front foot can be used to create a strong/smooth initiation move, and the back foot can add steering and shaping to the turn. Might be hard to picture, but putting it into practice is fun. Thanks again.
