pin next to cg isn't a blem or a second. It's a first quality ball, with a short pin.
Many lighter weights use a pancake weightblock instead of a real core.
I'm not sure if the Pluto does this or not, but the 12lb rendition does have an extremely high rg, and a very low differential
2.67 and .017 So even with a pin far from cg, it's not going to have much based on the core.
What's the top weight? With a low top there's a good chance it's still simple enough to drill strong, it will just require alittle work.
