WCS seems to be more popular than ECS.  That's my impression from your site as you teach more WCS steps.  May I know why WCS is more popular?  I recently learned and now dance ECS and I like it and the dance music.  From where I live (Philippines), folks neither dance WCS nor ECS but they appreciate ECS type of music (mostly rockn'roll), and so dance to the music no matter how.  PS. would love if you can provide ECS patterns in your 'move of the week'. thnx.
