For me all 3 new cards are pretty much equal. SR will be stronger, has slightly better poses (for my taste) and i like green hair alot, while cute/sexy girls green hair are somewhat rare. Though, i also like blue hair (these two are actually my favourite colours) but she kinda has the weakest artworks (for me) since nipples are not fully shown. And the redhead's artworks|poses are in between green and blue in terms of quality (for my taste) but i don't like red hair. So yeah, going for SR first an then gotta see the prices and max sed of both Rs and then decide which one to buy first and which one leave for "maybe, if i'll get enough shards for that too".

Still, didn't quite got your point, Dragon. You like her the most because she has bigger boobs (or, rather, because they look bigger) than those of the other two girls?
