I just stumble across a box and opened it up and voila the same ball! Virtual Energy!
As you probably know it is the hybrid version of the Virtual Gravity which was a solid.
I had many friends used the Energy for a long long time and loved it. I don't usually have luck switching from right to left and I would guess vice versa on Assym balls but it can't hurt to give it a whirl! The price is sure right!

PS it looks in great shape! I may have mine drilled soon after seeing this post!
