I drilled mine last night. Pin 5" to PAP (under my bridge). CG 3 1/2 to PAP. Hole down and inside my VAL. 

 

EASY through the front of the lane and good downlane reaction. If anyone has a Resurgence, Momentum, Momentum Swing, Burst or Outburst and likes the roll of those balls, the Eruption is an absolute must! Good luck to all!
