Right when reactives started to flood the market, I had bought a Gyro Pro (pea green) and drilled it leverage. Oil volumes weren't what they are now as this was around 1992-93. Man that ball was awesome when the lanes really hooked.
I bowled a Saturday afternoon travel league at that time. We dealt with conditions of following juniors throwing house balls and plastic down the middle to houses forgetting we were coming and last dressing them the night before for first shift. This Gyro Pro (was an old school 3 piece block) was just awesome. It got down the lane better than the urethane Turbo I used to carry with me.
Some of the newer ones for me were Roto Grip Mars, Brunswick Blazing Inferno & Punisher, Ebonite Shockwave and Stinger, and Storm Jolt and Jolt Pearls all rolled well for me on dryer or shorter patterns.
