ABC Poker Still Effective?

[TheJokerIsWild]

What's the highest level that a 6 man NL player could play "ABC" poker and still make at least 3 bb/100?

Assumptions:

1. Online--American sites
2. You don't tilt or tilt very little
3. You have expert bankroll management
4. You can handle variance

So basically if you are mentally stronger than your opponents, but play basic ABC poker, how high could you play effectively before your opponents figure you out and exploit you?
