Scroggins used the Virtual Gravity plus a purple and black ball that did look like a BuzzBomb but couldn't have been, as noted previously. Neither Buddies nor the PBA show the balls used on today's TV show even though it was completed a while back.
The only other purple and black strong ball is the B'wick Maxx Zone. It did seem stronger than his VG, so it could have been that. I don't believe Scroggins has a contract with any one company.
