I would say from the video that #2 was weaker and the non-existant flare rings shown in the video would confirm this..
I don't know why though.. cause if flare is determined by RG differential I would think closer to the pin would be less flare. Drilling right into the top of the pin will lower the high RG of the core the most thus lowering the overall differential and thus lowering flare.
The placement on the other side of the PAP might have something to do with MB and asymmetry... kind of like putting the MB/PSA spot past your track which puts the other MB/PSA (on the other side of the ball) in a similar spot to the #2 weighthole..
when I have seen this done it really kills the reaction.. I heard that the ball will sometimes flare backwards..
A weight hole is like a PSA spot.. at the spot of the weight hole it makes that spot a high RG axis..
