RE: shooting on the exhale???
Man, you guys are cooler (I mean in the patient, under control sense) than me! I'd have a hard time waiting and observing such subtle sign once I had the gun on target. My first thought is that if you're looking at the balance sheet of good things and bad things, the potential for bad because of the thing moving or spooking while you're waiting for that exhale far out weigh the good of a potentially quicker drop. Both are potential effects and I just don't see an over riding reason to wait, once you have a good shot.
