Sizing Vicky hair to fit on Dina is extremely easy... The problem you mentioned is a bug and can affect hair even on it's NATIVE model. Sizing hair in general to other figures is easy... I just used the M3/David "Morning hair" from Daz, on V2, and it looks great. I've taken to using Dina again lately... If ya can manage to pretty her up she is a great figure. She has problems, being such an ancient figure though, particularly in the shoulder and elbow joints. Still I like using her.
