laying the ball down early or spotting early (say the dots), will get the ball to roll sooner.. especially if the ball being used is stronger in cover or grit/sanded.. it sounds to me like the ball was rolling out before it got to the pocket.. when you friend lofted the heads(to the arrows) he took that whole section he tossed over out of play.. the ball never gets the chance to read that part of the lane he tossed over, so it will save more energy and have more strength in the backend to recover..
