I just picked up the Particle with nice results. It is pretty strong at the OOB 1000 surface, I actually added a light coat of polish to it and it still reads the midlane very well. Not a ball you can wheel, at least I have not had success trying. What I like best about it is it evens out the reaction when other balls are either jumping off the spot or fighting the carrydown. A nice ball when the conditions are right to just pick a repeatable line and watch the ball do all the work
I drilled mine exactly like my SS, pin over ring finger and a slight swing of the cg. Unless you really bowl on WET conditions or have very firm speed, you may want to keep the pin up to try and get some length.
It's a really nice ball, enjoy it and bowl well. I am sure a few of the guys here can help you out with the BGC.
