Is there any reason to believe that that's the trickiest party? I know HT did it but they have deep pockets and nobody else has attempted it seemingly -- though didn't the original underscaled Tama have a metal
dome?
Still, I saw the Tama in person once behind glass at Midtown Comics and the dome seemed fine. Better than the SS, no seams, and the overall size is great. I think my only gripe outside the dome not being metal would be the notches for the panels, and the tools look weird to me but I don't really care about those since the HT ones look great. Rivets didn't bother me much, even though they are a tad too visible.
If I were to have two R2s, the Tama might be the one I'd want. I currently have the TFA version boxed up, had been undecided on what to do with it. I suppose I could sell it and pick up the Tama.
