Speaking of different bodies, I was going to swap arms with one of those "speedo" bodies and was annoyed to find the arms aren't compatible with the regular arms. I'm sure you already know this, but it really reduces what you can do with that body type. Are the arms of the teenage bodies compatible with the regular arms?
The arms on the speedos are only good among the SAME GENDER. Speedo male and speedo female arms. Yes, you read that right. It was a bitter disappointment.
I didn't pop any of the new Super 4 bodies.
The fairy seems radically different. INCLUDING THE DARN HEAD. So I gave that up.
Alex, Gene and Ruby I don't have repeats, and don't really plan to anymore. From a posted link, the heads are different too... and to me, it looked like Alex's arms are male speedo arms. This from looking at the pic. Add to that the silly left+right arms, and... bah. I think right now, these are useless for customs. Except Alex and Ruby's hair, of course...
