well to start i just started bowling seriously for about 5 months ago. i just got the arch rival a couple of days ago, and it is just great..... the second game out i threw a 277 i got the first 9 x's in a row then whent 8/9 in the 10th. i dont rev the ball up alot yet,i usually just lay it down on the 10 board. i noticed that i had to move over 3 boards to the left and throw at the same target, had to get it to swing alittle, other wise it would just go brooklyn or nothin but head pin. this ball has alot of pin action didnt leave alot of 10's hangin in the corner,i threw it with the out of the box finish, i dont exactly know my layout but im right handed, pin is just above the ring finger and to the right, it also has another hole drilled in the side to make it legal to throw, i would recommend this ball to anyone who is just starting or who has the experience...........
