My drilling reference

this is usually where i get my drilling reference from

cos i am very limited in my knowledge of ball drilling so this way of drilling the ball with the distance to the pap and the distance to the cg or mass bias with the pin buffer is the easiest for me to understand

cos i dun really understand the degree drilling reference

and i think most of the bowlers will have a better level of understanding of what i am trying to tell people about

maybe one day someone will be kind enough to teach me how to read the degrees drilling references
