Mine was most effective on heavy oil. I never even tried it on light oil as it would burn up on medium. Maybe if you took it up to 2000, but not really what the ball was designed for. If you want something for dry, find a 3-D Super Flip or a 3-D Violet Pearl. I still have both of mine and they're great on lighter oil shots. Good luck finding one though!

Is this the one that has the distinctive purple color???  If so, I have had success on med oil, but I've also been able to use it on late nites when there was very little oil left just by increasing my speed.  I liked using this ball because even if I increased the speed, the ball did not "burn up" at the end and still had plenty of hit left under these kind of conditions.  Hope this helps.
