William, Seriously, shot #2 is a nice grab. If you've indicated whether the 600 is an AF or MF, I missed it. Do you have stalking "wildlife" plans or to just check your reaction to random "compression" shots until a direction happens? While I have no experience "hints" to pass along, I'm certain you're going to add a number of dramatic images to your inventory by its use. Best part, a new lens,..etc, always stirs the photo juices anew.
