Wow. I usually read these and go nuts wishing I could get the figure.
This time, I have the figure in question, and I'm still blown away by your review and photos!
I head swapped mine; he looks awesome with the movie-Duke head they'd originally planned to use, and with the Outback head, as well.
Also, if you have the Cobra Island Outback figure, this Duke head looks
amazing on him!
EDIT:Here he is with the movie head:

For some reason or another (and I'm seemingly the only person in the world who feels this way), I actually prefer this head on him. I love the existing head sculpt, but something about the realistic look of the movie sculpt lends itself well to the grittiness of the body sculpt.
EDIT 2:You mentioned his awesome backpack in some other thread, and I remember thinking, "Huh, I don't specifically remember it. I must have left it in storage in Idaho." (I have to leave most stuff there; luggage space is scarce!)
Looking at it now... I don't recognize it at all. I hope I didn't accidentally throw it away! I guess I'll find out next summer.
(Incidentally, I hate when the backpack is hollow, and you can see the hollow bits sticking up past the figure's shoulders. Lame!)
