ADC masteries: Where to put your points?

A simple question for discussion:

Where to put your mastery points as an AD carry?

My personal take is to put 18 points into Ferocity, obviously. Attack speed on tier 1 over spell damage. I personally prefer Feast to Double-Edged Sword on ranged champions. The mastery gives you a decent amount of sustain in lane, where it realistically translates into 3-4 Hp5. When planning to buy Doran's Blade, I go for Natural Talent. Otherwise, I tend to take Vampirism for the scaling sustain that you're lacking with Cull or Long Sword. Bounty Hunter on ADCs that are more likely to get a lot of kills. Oppressor on more utility-based carries, especially Ashe. Armor penetration and Warlord's Bloodlust for Tier 3, obviously. Although the upcoming limitation of Bloodlust's effect makes Fervor of Battle more attractive, even to ADCs.

The remaining 12 points are what I find particularily interesting. Both Cunning with its increased early damage to minions and the HP restore on kill/assist and Resolve with its reduction in damage taken and the lower summoner CDs seem attractive.
