and a big thanks to Deb Armstrong for taking us along on days like this.
This is an example of what Deb A refers to as 'over baking things'. Perhaps of baking the wrong things.
About 7.5m into the VDO the Mahre brothers clarify the orgin and practical use of the White Pass turn. In their words -
'Its a mistake resulting from a tactical mistake'
'You cant do it consistently'
'No one needs to practice the WP turn'
I submit the WP turn drill is really one of many useful & not so useful agility & balance drills for developing racers, may be high end skiers.
I also suggest dryland work such as one footed hopping drills on a rope ladder on the floor or, the more challenging one footed hopping on a single or multiple bosu balls is a cheaper more effective way of developing agility & balance. Then if you really have the need to do a WP or a Charlston drills on the slopes knock yourself out. Better to hone your body in dryland and save the money and time for enjoyment on the slopes IMHO.
