That's because the heads are different.. isn't it?
Wonder if it's the combination. Will have to try that.
Yes, it is. Old heads can be used with the new frames, but the new heads not with the old frames.
My personal opinion is, that the new inner frames hold the figure much better. Many Romans (and other new figures) have problems with the hip, but the Fi?ures stand very well.
