Both versions seem to have pros and cons. I have to say I'm leaning toward this version overall, but I need to see the finished colour version to be sure.
Fake chest doesn't bother me, as Wardog essentially fakes his gun turret chest but the ingenuity and implementation is awesome, so it wont feel like a cop out for me as long as the engineering is clever. So far Badcube's transformations have been complex but always rewarding, so that and the quality of their last release has me favoring this one, at least for now.
