quote:You are right Trig I did not invent the lay out and yes I have been credited with it because of use at certain events. The way I have used it with asymmetrical core balls is, since the mass bias reacts similar to a weight hole, where the mass bias differential is high enough, I place the weight hole, if necessary, along the pin to mass bias line at the horizontal axis coordinate and have gotten desired results. Weight holes tend to alter asymmetrical core balls less than symmetrical, so for the most part, weight hole placement in an asymmetrical core ball will have less affect.No I did not 'invent' this layout but I have used it numerous amounts of times in many different rolls and have had very good success.--------------------Ric HamlinPacific Northwest Product SpecialistBrunswick BowlingAKA "Rico" and L.I.M.O.M.
