The Doom can work on light to medium lanes if it's drilled properly. Other possible choices would be Track's Solution Power Plus Ex, Heat, Ebonite's Crossfire, Roto Grip's Saturn or Venus. For heavy oil....The Hawg is great. The Hawgzilla is getting lots of good press, Track has the GP2 and the Robo Rule, plus the new Mean Machine coming soon. Ebonite has the Big One or Infinite One to choose from. The Epic Battle is a good ball as well by Roto Grip as would be the Visionary AMD Centaru Solid, or the Partical...if you are on really heavy oil that is. Storm's Passion is also a good heavy oiler.
If you want to go to Hammer.....The Doom is a wonderful ball as is the Hawg or Hawg Zilla. You won't be disappointed.
