Your description means nothing without PAP coordinates. It would mean two completely different things to a spinner compared to a high tracker. It's already drilled. Throw it and you'll have your answer. A little late to be asking drilling questions after the fact, isn't it?
To me, "CG in line with pin, 2 1/2" down" implies stacked, but then you say it's in your palm. Which is it? The first would probably need a weight hole to be legal. The second would be OK.
