It was a medium-light oil ball with a Quantum-type mushroom core. I found it very versatile, because of its mild coverstock yet low-ish RG core.
My best memory of it was one day during a fairly competitive league, the house shocked everyone by using a medium-heavy oil pattern when we were all used to bowling on medium-light oil (when we were lucky). Many people using particles ball and very strong oilers like the Scorchin Inferno, were totally lost.
I found a tiny bit of dry going directly up the 10 board, which was highly unusual for me. It was fun outscoring the house hacks that night. with the 210-220 average "champions" shooting 550 if they got lucky to my 660.Wish I had entered more pots that night.
Today, it would definitely be a light to maybe medium-light oil ball. That mushroom core will help a lot.
Don't be afraid to drill this ball pretty strong - it never overreacted.
