I would say in general you need more hip-turn and less hip-slide in the downswing, a little carry and a little tumble with that turn will help get a little more descending blow with a higher VSP. In doing this you may want to weaken your grip to eliminate a pull since your path will be further left, but I'm guessing doing those things will help make better contact and produce a nice boring flight. Don't be afraid in practice to feel like you are sticking the club in the ground, with your straight left arm and athletic shoulder turn you will be able to find a happy medium in shallowing out the attack with the proper VSP.
