It was a big factor for sure but we know there should have been a size difference between T1 and T2 anyway and so the more sticky-out MMS117/136 chest was always going to work better on a T1 figure. And the situation is better again with consistent head-sizes which Miltiadis has done here. I'd do it, I'd return to the MMS136 head if only I could at least get rid of the blood on that sculpt.
