Part of it is in the eyes. Roselyn has those "I'll-suck-and-fuck-the-shit-out-of-you" eyes. Ashley has an innocent face and doe eyes. Her eyes say "I didn't do it; I promise" and you'd believe her. She has a "good girl" look whereas Roselyn looks like a seductress. Add to that her low, sexy voice and you've got a mistress. Ashley looks like a high school girlfriend on the cheerleading squad.
Its just my opinion. Some will relate. The innocent-looking chicks tend to be the worst ones, btw. Facts.
Had a thing for Roselyn for a while... and given the ages and the fact that she still competing. I'm rolling with Roselyn. Otherwise Ashley would win just for having nudes.....
