Well, if you're only gonna take 3, you want to cover it all. If money is no object, I would go:
1. Ultimate Inferno box surface with a strong drill.
2. Polished original Inferno with a pin over bridge type of drill.
3. Polished Bruiser drilled mild.
For a slightly cheaper but effective arsenal:
1. Warp Zone - polish or dull as required.
2. Bruiser in your favorite layout - this will see the most usage.
3. Reactive Chrome/Yellow Power Groove.
A 3 ball limit sucks. I'd have to leave the Eliminator home
- or worse yet, the Monster Red/Black
