Check out the video I submitted to videoballreviews.com that shows the Second Dimension compared directly against an identically-drilled Dimension.  Granted it's on a heavier oil pattern (a fresh sport pattern actually), but it gives you an idea of how the motions compare and how much more angle the Second Dimension generates downlane.  And, the Second Dimension surprisingly is very resiliant to burning up and rolling out despite being able to handle more oil than most pearls.  It should be exactly what you need between the Grand Illusion and Dimension.

For the record, on nights when I see enough oil to throw the Dimension first, I switch to the Second Dimension once it starts to lay off on the backend, and I'll move two or three boards further left to accomodate the extra backend reaction.

Mike,

I initially was using my 2nd as either a short oil first ball out of the bag or for transition from my Virtual.  Lately I have been using exclusively as a transition ball from my Dimension and that is working out the best.  I would agree with Dan's concept of moving a bit left to account for the additional backend.

I have my Dimension at 5x3 - 1000 abralon and my 2nd at 4 1/2 x 4 - 2000 abralon.
