I prefer QJo:
Let's say he calls pf and then flop is:
1) Ace - King high: he checks, you bet, most of the time he folds, if he raises it's an easy fold. If he calls I'd bet the turn too with the intention of check-folding.
2) Queen-Jack high: you are probably ahead.
3) Other flops: 2 overcards, I bet flop and turn...
