I find it an interesting question too as we study with 2 teachers in different eras.
Teacher A: 70, former national champion, ISTD Fellow/Examiner/Life Member, 7 times judge at the world championships.
He lives elsewhere but visits here about every 2 months for about a week. We take as much time as possible with him when he's here and he's coaching me on an ISTD and CDTA certification exam.
His philoshy: It's all about what you do first that gets the lady moving. If the man does everything correctly essentially the lady has no choice but to follow correctly.
Teacher B: 36, new to Canada, trained in Russia, competing at Championship levels and aiming for BlackPool.
Philosophy (and style): He places more emphasis on the lady's contribution. An over simplification but whoever is on the outside of turn is the leader. The lady therefore takes a more positive responsibility for her own steps.
If I were to make a barely knowledgeable comparison I'd say Teacher A's style is more graceful while B's is more athletic. So is it Dance or DanceSport?
I will say that there is an inherent level of less stress in teacher A's approach which I prefer and think should be.
But I'm getting something from both.
