This has been one of my favorite builds of all time. 3,4,0,2,7,7,7,3. The high reload and penetration boosts you, as well as creating a formidable bullet shield. You can outmaneuver overlords as well as destroy octotanks. As an added bonus, you can dodge dominator bullets while shooting them with your sideguns.
If you want extra speed, go for the booster. It helps when killing drone based tanks.
