Let me just say both 'Oooooo!' and 'Aaaaaah!' I was 90% sure I would end up buying at least one of the omni centurions (well, most of the current crop of releases actually), but I wanted to wait and see the final product first. I like what you did with it, as the TRO art just felt a little chubby to me compared to the non-omni Centurion. I can see how most of it just got taller, but it looks like the waist/hip area is a fair bit different. Much less of an apron/genital-shield type of look than the TRO. Not saying it is good or bad, just different.
Oh, and thanks for the extra heat-sink. I still hate them and will glue at least three solidly to my fingers instead of the arm, but I can't argue that they are neat details once they are on!
