Being a true high-load particle ball, I don't believe you are going to see a lot of movement in the back part of the lane with a Goliath. Your not going to get the recovery of the Strike Zone (solid resin) with a high-load particle because that is not what a high-load particle is meant to do. High-load particles start to roll early (a good thing on really oily lanes) and the movement to the pocket will be very much an arc shape.
Wasn't this all explained in a post labeled "Particles 101"?
Anyway, when a high-load particle is hitting weak it is using up all it's energy before it hits the pocket. This could be from lack of oil or trying to make the ball cover too many boards.
