Well, this is what I try to do. Hope it makes sense and helps.
·Good timing to the line (properly coordinated hands-arms and feet movements)
·Getting low as you hit the line
·Waiting for the ball once you've hit the slide
·Staying low at the line with sliding knee AND ball hand upon release
·"Chasing" the ball onto the intended target with the hand (following thru flat at the bottom of the swing
·Once the hand reaches its outward finish it naturally goes up with the momentum of the force of the follow-thru (finishing toward the ceiling, but NOT over the head)
·Watch the ball pass the intended target before raising from the line (instills proper body balance)

If it is to be, it is up to me.
