Loved the vintage Hoth Trooper... He's another one that, for some reason, lived on into my GI Joe does as a Cobra scientist in biohazard type gear working on the evil Cobra biological weapons my warped child-mind had concocted. All this reminiscing makes me think I was a messed up little dude.
The Kamas were long gone on mine though, but he's one figure whose gun somehow survived to this day (lacking the forward grip though, for some reason). I still wonder where the hell the design for his rifle came from. It's very unique. I've outfitted repro's to some of my custom modern figures, actually, as it's such a unique sculpt. And newer figures hold them great with better articulation and such.
For modern, the "Vintage" Snowtrooper still ranks high on my fav figures list... A cloth kama, super articulation, removable helmet... It's amazing. My only disappointment is I'd love to see them do the helmet, but with a cloth face-mask attached. Difficult, but not impossible. I'd pick up some of those, and maybe give it a go myself someday just to see how it looks.
Some of my troopers have wide stances, otehrs don't. It's a weird figure that way. I've gotten a couple with stances so wide they could ride a taun-taun fine, and others are quite narrow-legged. I'm not sure why that little enigma is other than possibly a difference in molding or packaging possibly stressing the limbs when they're still warm?
