I think you should reread the post he said that "Slashing" can be used as an effective braking technique not for turn initiation.
I'm having issues with this aspect of my riding, my problem has to do with part of the turn initiation. Once i get my edge set I seem to be able to hold it throughout the turn but it's during my edge change and getting that edge set is where the issues arise. It almost seems as if my rear leg rides really heavy(Not in the sense that I'm riding backseat) and struggles to come around. I think a better way of explaining it is that my read leg seems to take a larger than normal turning radius and does so very slow. It's not as much of a problem when I'm in an open area as i can just grind out the turn over a larger area. But when I'm in the trees is where it's really an issue as I just don't have as much room to complete my turn and require a quick edge to edge transition. I'm just more less wondering how i can bring that rear leg around quicker and set my edge to prevent slipping down the hill? I'm thinking it has something to down with unweighting but I'm having troubles understanding the whole concept and how to do it.
Try a couple of things:
First, work on using a down unweighting maneuver versus up unweighting. An up unweight is basically a rapid extension of the lower body to pop up thus momentarily unweighting the board. A down unweight involves a sudden dropping of the upper by by rapidly flexing ankles, knees and hips. When you do this rapidly, there is a briefer period of "weightlessness" and your board remains in contact with the surface. On steep terrain, this keeps your entire body lower and closer to the slope, improving your overall balance. The down unweight to make the edge change is a huge help for making these very quick and positive edge changes with minimul time where the board is not weighted on the snow.
Secondly, start playing around with good fore-aft movements. This accomplishes what the kicking of the tail out weakly tries to accomplsh only much easier, more efficiently and way more effectively with the added benefit of maintaining a good set edge in the snow. Unweighting the tail is what causes the board chatter at the bottom of turn.
So, when you come out of one turn and are ready to make your quick, positive edge change, rapidly drop toward your board and use the ankles (angulation) to accomplish the edge change. As soon as this occurrs, you are initiating the turn and your weight should be shifted forward over the front foot. The reason for this is that you want to get that edge set early in the turn and the added weight up front does this very well.
As your board enters the fall line in the control phase of the turn, shift your weight aft of center to set up for good, quick turn completion. The reason for this is that as your travel through the control phase to the completion phase, your momentum down the hill combined with your weight, combined with the centrifugal force generated by the turn all come together at the bottom of the turn with a hell of a lot of force trying to break your edge free uncontrollably down the hill. The increased weight aft greatly increases the edge hold and drag and keeps the skidded turn very controllable
I just worked with this tonight to negotiate medium sized bumps on a 40 degree pitch in one of our bowls. It is amazing how quickly the board turns in control and how slow you come out of each turn. I was able to ride a zipper line down through the bumps; riding the troughs created by skier`s lines and was able to manage speed giving me the time to turn the board around between bumps.
