It's great. Currently you can run Adamant (outdamages Life Orb Jolly Aerodactyl even on non Tough Claws boosted moves) and it still naturally outspeeds everything relevant except Mega Manectric. Tough Claws gives it great coverage moves in Aerial Ace (Sky Drop if you want to play stall), elemental fangs, Iron Head, Crunch and Aqua Tail. There are defensive stall breaker sets too with Roost and Taunt. Very anti meta for the most part, outspeeds and can OHKO a lot of common OU threats like Mega Zards, Talonflame, Mega Pinsir and Garchomp.
Once ORAS comes out though it might not be able to afford running Adamant anymore with the Mega speed creep. This doesn't mean it becomes trash though, with Jolly it can outspeed and kill the newer threats like Mega Lopunny, Mega Beedrill, Mega Gallade (though it already outsped this one with Adamant) and Mega Sceptile.
Give it a try, it might surprise you.
