Thanks for the info on Isla RandomGuy. She's another one that's not a million miles away, so is on the hit list.
As for the type of girl that has large or protruding flaps, I've tended to believe it's the skinnier girls that have these. However, it might be that their lips are not particular huge compared to larger girls, but they tend to protrude/hang/standout more, simply because the girl is so thin/tiny. It's a bit like skinny pregnant girls, you tend to notice the bump far more on this type of girl imo. Be interesting to hear what others think.
