I have Daisy Dreams with bangs, but I think the Fluttershy with her has light pink hair (At least I am pretty darn sure since I remember her being the only light-pink haired one that I have, except she is tucked away back home and not with me so I cannot double check... And DD has bangs for sure!!). I didn't know there were two types of this set, though. That's interesting.
I am not sure which one would be rarer- it is said that ponies with bangs are rarer because they are the first release, but in my area, ponies with bangs are still being sold. So it's hard to believe they are rarer (but maybe just old overstock?).
