With these balls having both high RG differentials and an apparently fairly strong mass bias, unless you have a good amount of oil or a higher ball speed, they may wind up not hooking a lot at all, especially the solids. While I would recommend a 6" pin to PAP, for anyone with decent revs, I'd recommend pins in the 5" range, more or less, and be careful where you put the MB marker. It is of secondary importance to the in's position but its correct location is very important.
I found even the AMB pearl, the golden one, needed a fairly long and high pin to PAP and a decent amount of head oil, to conserve energy.
