(For whatever it's worth: )
I'm currently using the Power Groove pearl and solid combo, on Brunswick AnvilLanes oiled light to medium-light. Their breakpoint is not the uncontrollable backend that many people make them out to be, IF drilled properly but not unusually. Their hitting power is in line with other Brunswick products.
I believe their RG is slightly higher than most out there right now, and the PK 17 coverstock, in both solid and pearl version can hardly be bettered.
RG Max: 2.704
RG Min: 2.663
RG Diff: 0.041
