I bought a Pathogen and drilled it pin down work just the way I wanted big P-4 hole to make it real strong . I then bought a Divergent Path and drill it the same way but with the weight block being a total different block when I went to put a p-3 hole in it it did not have any thumb weight. Because of the style of the core so I just made the ball legal I put the hole on my pap. This ball works great for me first out of the bag.
Have your driller weigh it after layout.
