[SPLIT LIP]

Yes the legs can bend 90 degrees forward. It's actually quite a simple ball socket in there, but due to the form swap gimmick the hips have a tiny bit of swing back and forth which makes it far easier to get the top of the legs under the skirt then I imagine it would have been on the original Cyclone Joker. (but still possible)

And while I can't speak for every SIC past double, I have Tajador of OOOs fame as well and he is emmaculate. (sp? I've never had to spell that word before) He also has unhindered thighs, ven less so since his skirt armour is more traditional (parted just above the legs) and he can actually do a bit more than a 90 bend at the hips, due to a ball joint in his lower waist. As for overall quality, these things are top notch. I haven't discovered a single issue in construction, or even paint slop. The only thing I thought was an issue about Tajador that I now see as a positive is that his belt and skirt armour don't peg in. They jiggle ever so slightly. However this seems to be for ease of posing and despite the jiggle they never sit unaturally or crooked. If Every OOOs SIC is of his quality you have nothing to worry about. (however I heard something about Tatoba having some kind of minor issue, but as someone pointed our before in this thread it's something about the way the legs are sculpted not allowing for perfect straight-legged stances where both legs are parallel)
