Got a few heads from Jesse today (still waiting on my vest, etc), and started working on a standard Spec-Ops soldier design. I'm diggin' it... maybe you will too!

I thought it was the Night Fox head. I have a few of those coming soon...along with a few of your vest and helmets. Very psyched for them all.
I will probably borrow a bit from this guy...you know...like I normally do.
I see different ball joints in the ankles? Revoltech joints?
That answers part of it...but then adds a new question...I take it the double ones are not what would be used since most of the singles are back ordered?..or could the doubles be used if the center peg was cut thereby doubling how many joints you have?
And again, what sizes are best?...I think I saw 4, 6, 8, 10...
I'm using 4mm for the wrists, and 6mm for the ankles and elbows - on Batman. On Joe stuff, the 4 mm works well for ankles too, depending on the size of the boot/foot/whatever. Shock trooper for instance, can use the 6mm for ankles since the boot is thick enough in diameter. SE has thinner boots, so the 4mm worked better. Like anything, you just have to eyeball the part and see what will work for it.
