WAG Hurdle Step Technique

[GymnasticM]

What is the best technique to use during hurdle step for optimum round offs. I've seen videos with several different hand placement etc

As far as hand placement goes, I learned to do it with fingers both facing the same direction like doing a cartwheel on balance beam.
However I later had a coach who wanted T-shaped hands where the first hand faces out like above, but the second one turns in to face the first (making a T, but hands not together). I never quite got this down since it was introduced quite late and never really worked on.
