I have my Dark Star drilled 5x5 with the pin 1/2 inch over the bridge and the CG 1 inch under the bridge, polished box finish. The ball gets down the lane very nicely and goes a little longer than most medium shell balls, it makes up for the extra length on the back end with a strong continuous finish and hits the pins with a lot of saved energy. Because of the extra length and strong finish I get better angles into the pocket when I'm trying to hook the ball anywhere from the third arrow and out. Its a great ball for medium to medium dry lanes and you are looking for length and backend. A must for my tournament arsenal and a great house shot ball at a low price.
