my AM has been extremely helpful to me, especially when I was getting started. In the beginning he spent most of the day with me going over the basics of ppc in general (i was doing seo previously).
now that i'm off and running (and probably making him a ton of cash) he's always there, gives me bumps if I ask, answers questions immediately, etc. If an offer is on fire he tells me, if an offer is sucking he tells me that too.
I don't give away any secrets as to what i'm doing, only general statements most of the time. a good AM won't ask you to tell him what is working for you, he'll know better.
