Well, I'm not really worried about the CG - I'm sure the pro shop can find that. I'm more just intrigued as to what the ball really is. Lets say I drill the thing up and really like it - I mean, its the best ball I've ever thrown. Somewhere down the line I decide the ball is done and needs to be replaced. How do I know what ball to replace it with? I won't have any idea what core it is or even the coverstock. Will I just have to cut the thing in half to figure it out? (and, what would I use to cut it in half?)
Some people have a preference for a certain type of core, as we all know that the cover can be played with to get the desired reaction. I seem to have better luck with symmetrical cores.
I think both balls look really good and they seem to have decent top weight and the pins look decent, so I would guess they are color blems.
