After looking at the picture of both the ball and the layout you want, you will be fine with this ball. Because of the lower top weight, you may not even need a balance hole. As long as you keep the pin bellow the fingers (which is one of the things you would want for a control ball for heavier volume sport patterns) you will be fine.
The only way I would recommend sending the ball back, is if you throw the ball very hard without many revolutions. The reason I say this, is because you will need to have alot of surface on the ball to keep the ball from going through the break point. With the shorter pin, you will not get as much backend with this ball with alot of surface, as you would with a 2-3 pin ball. Even though it is a mass bias ball, The pin in means that the core is positioned towards the middle of the ball, giving you easier revs in the front part of the lane. When a ball has the pin farther out, the weight block is "offset" more and away from the center of the ball, giving you more motion later down the lane.
That is one more reason to check with your local certified coach or pro shop operator to make sure this ball is a fit for your game.
