I'm not worried about poses being tricky, every body has it's own workings to figure out, even the HT T-800 could do more poses than you originally thought.
My concern is joints getting loose and beyond tightening where it hardly holds and poses.
Almost all the joints are ratchet joints, so they stay where you put them, the jacket obviously hinders things slightly, but that's expected of any figure like this. I havnt done a ton of posing myself. Put him about 7 vastly different poses when i got him mixing up anything from walking, standing, a sort of crouch, arms bent, arms straight, endo arm on and off. I settled on a shotgun straight in the air sort of post. Joints are still super stiff and the ratchet joints are all still nice and...for want of a better word...ratchety.
I have stripped him neked, removed his boots and hands, forcefully bent his leg to level it out with the other...he's definately been 'played with' but as i said, all is well on the joint front. Whether that is true across all figures? Who knows
