Skate push - To the side or at an angle?

What direction should your skate push go? We get this question all the time, but the answer is not so black and white. The direction of a skate push depends on the skiers forward velocity. The slower a skier is moving the wider their V will be while skating. This is true in V1 and V1 techniques. 
When skiers are moving at a higher velocity across the snow we can afford to make our V more narrow, and this will affect the direction of the skate push.
