I set this position up on my table and on the first and only try I pocketed the 10ball off the 12ball and pocketed the 5ball in the opposite side. The 12ball ended up near the first diamond on the foot rail. Wow!! With two balls positioned near the top rail and the 8ball positioned deeply on the side rail it's much more difficult sending two balls toward your side of the table especially if the two balls are tied up near the top rail.This is one of those rare times when the balls lay good for the shooter freakishly positioned to where the shooter needing all four balls can bank the 12ball into the outside of the 5ball and possibly pocket the 10ball off the 12ball while sending the 5ball to his side in the process. Would I shoot this shot? You bet I would needing all the balls.
That's another reason I like positioning the 5ball near the 12ball on the top rail, it's very difficult getting creative with balls on the top rail as opposed to balls on the side rail.
