Wow, thanks a lot for those pics. That's very enlightening.
It seems that every different clone has something unique going for it, articulation-wise, but none really are a perfect version, which I'm sure is intentional. I'll be curious to see if the SA Clone #41 has the cool hip articulation from the Gunner. If so, I can imagine that I'll not only want to army build with it, but convert a few Gunners over to the SA body style.
