Who has a more amazing ass, Lisa Ann or ***** Cavalli? This is a tough one =)

I have been a fan of Lisa Ann's since the 80's and have watched her grow and mature well. Her ass looks great these days. Not sure if it's been slightly altered though. There were some signs a couple of years back that lead me to believe she may have had some implant work. If you need proof look at her first movie that she did anal in. You can clearly see two scar marks under each cheek which have since faded. Anyway enough about that. The question here is who has a better ass. ***** or Lisa. I would have to say ***** gets my vote. She's a little younger and her ass looks amazing and a little more natural than Lisa's. It was a tough call for me though. What's your opinion?
