Top weight is extra weight that is added to the ball to compensate for the weight removed by drilling the finger holes. the top weight of a undrilled balls can vary. 2-3oz top weight, or 3-4oz top weight are pretty common.
If you have the org. boxes your other balls came in, just look on the label it should have it on there.
Top weight is similiar to the pin to cg measurement in that it could have a bearing on the static weights and the layout you plan to use. Such as a high top weight with a short pin could limit layout options.
Most balls though come in a pretty standard range though.
Example:
A ball with a 3-4" pin and 2-3oz. of top weight. would work for most typical layouts.
Also the old idea was that the amount of top weight used made the ball go longer down the lane and snap a bit more on the backend. But the Usbc studies showed that this like the cg had very little effect on the balls motion, but there are those that still subscribe to the idea.
