First of all, hell of a job. That was fast, and in a situation like this one, fast counts.
Why limit it to just one decoy? They guy's mind is all over the place and if there's one thing I've learned over the years, it's that two rabbits to chase almost always beats just the one. I'm just sayin', if this is the plan -- and I think it's a good one, the more we can spread that guy out and keep him on his toes, the better.
As for how we go about it? Why not just relay the thing. Two satchels, multiple handoffs. It'll keep the guy's head spinnin' so fast he won't know who to chase, which brings me to my next point...
I want point on the switch. The guy doesn't have any shortage of reasons to come gunnin' for me as it is, one more to him ain't gonna make a lick of difference. Plus, bad ass as you might be Carol, I think it's safe to say that whoever snatches this bag ought to stay clear of the civilian residences for awhile, and I'd be willin' to bet that I look better with sticks in my hair.
