Ladder-specific builds

Lately on ladder I've been opening 7RR. Not because it's the perfect build, but because no-one (at my level anyways) seems to recall that it exists. This leads to a lot of situations where I'm wrecking their base and  they're saying "l2p noob!", which is hilarious.

But when playing against friends (who know I like 7RR) I've stopped doing it because it's not an optimal opening. So this makes me question my ladder strategy, and I'm seeking outside opinions. Is winning with 7RR, an early aggression build outside the current meta just being a jerk for ladder points? Or winning the meta-game?
