Yup just dribbling it down into the crack it'll secure it
Got hold of the pro shop on this one, and that is nearly what they suggested. In fact, I got hold of the guy who directly punched up the ball, and showed him the pictures.
Measuring it, and going off the specs he had for it, it appears to be 1 inch exactly from the pin to the holes, so I'm pretty safe there. I also described the crack to be no thicker than a business card, since that is what it is. His suggestion: Most manufacturers won't cover this under warranty (it isn't a defect, like a separated core, etc.), but if I'm loving this ball, plug it and get the fingers redrilled in the same location. The plugging will cover the crack anyway, and drilling it in the same place will give the same performance.
I'm probably going to go that route, and could have it done at my local pro shop here, as that is going to take a couple of days anyway. I could try to do it myself, but there's the liability thing; if the pro shop does it and screws up, they'll be on the hook for replacing the ball, not just me being out of the ball to begin with.
