Why do you never use the sidehill bar or a left hand throttle?
The sidehill bar and left hand throttle are great tools for the average mountain ride. However, you can't change your direction on a right to left hand sidehill with being able to change the direction of your skis. With a mountain bar you are stuck holding the skis in one position-straight. To take your backcountry skills to the next level, take a day and focus on doing right to left hand sidehills only without using that silly mountain bar. Counter steering and throttle control are the two most important things to focus on. Foot position on the sled and sticking your opposite foot out for balance will be next on your agenda.
