I always like fights that are competitive and always nice with dirty moves allowed. I don't care who the two girls are if I find them attractive (blonde, brunette, love redheads, love Asians, latino, Native American, skinny, curvy, big breasted, big boned) and the scenario/match up is good.
Of these matches, my personal favorites are
1) facesit fight, love when competitive and one girl gets a girl down and smothers out a victory (prefer reverse)


2) I picked preppy vs goth (or punk) for my second because I do have a thing for goth girls and seeing one take on a preppy or plain girl is a nice sexy contrast.

3) Lastly I picked 2 vs 2 because recently I have been cybering a bunch of couples fights and tag teams which can be fun to see two girls beat down another team (maybe sisters, mother/daughter, airline stewardess, teammates, etc) and dominate them.

There are also a number of other types of fights I like not mentioned like Battle Royale catfight, team catfights (like two cheerleader squads, 2 basketball teams, 2 sororities, etc), Asian vs Redhead, etc...
