Hello. Rob Butler is a CSIA Level IV. Although he is a little "old school", all of his ski tips are based on CSIA doctrine and methodology. He is "old school" by virtue of his being around for many, many years. His teaching accurately reflects modern skiing principles.
In Canada, instructors are trained to teach within a skills framework. There are numerous approaches to "detection and correction", tailored with teaching experience, personal preference and the student's needs/goals. However, for any "correction" to become valid, it must first get churned thru the skills framework.
Our core skills are stance and balance, pivoting, edging, pressure control and finally, timing and coordination. We speak often of "blending the skills", because skiing is a very dynamic activity. At the rudimentary stages of skiing, skills can be more easily isolated individually. As skiers develop and become stonger, more blending of the skills becomes necessary.
Rob Butler's tip takes two separate skills and sets the stage for blending them.
PIVOTING + EDGING = STEERING
A highly refined pivoting skill is one of the hallmarks of EXPERT skiers. Without a perfect blending of the skills of pivoting and edging, perfect steering does not happen.
Rob's tip took you to the very beginning of this process... the skills remain separate and distinct while joining forces to create a whole new world of possibility.
