After thinking about this for awhile I've been wondering why people would run Choice Band on the Fake Out version of Ambipom. Wouldn't doing this force you to switch out regardless after your Fake Out? If you run Life Orb you get to Fake Out and then, if you are faster, U-Turn into a counter for extra damage. The recoil damage problem shouldn't matter much since Ambipom will probably die from most attacks anyways. This would also allow for Fake Out followed by a King's Rock Double Hit if you want to go for Flinching or if you think you can kill the pokemon. If Double Hit gives King's Rock two chances to flinch, it might cause Life Orb to trigger more than once. I'm probably leaning towards King's Rock if I use Double Hit, Life Orb if I don't.
The only other thing I'm wondering about now is Pursuit or Shadow Claw. After Technician Pursuit is 60 BP compared to Shadow Claw's 70 BP. At first I thought Pursuit would have been better cause it has the chance to do double and hit on the switch if you think they will run. Now as I'm typing this, Shadow Claw also has the chance of doing double and probably not many pokemon will be running from Ambipom. I'd still like to hear people's thoughts on Pursuit.
