what ball is it? i just drilled a jolt pearl negative with about a 3-4 inch pin. LAYOUT, i placed the pin roughly 1-2 inches above my bridge( dont know exact distance) i then kicked my cg below my middle finger as close to my center line as possible. no weight hole was needed. REACTION, the ball flys through the heads, and has a strong backend move. i was very surprised to see this out of the ball. but, the ball does clip the thumb hole. but dont worry, many people that throw a "negative" ball will clip the thumb hole, just an idea. And remember, the higher you place the pin, the more length.
