1) As happens in many other productions, yes, the girls know each other, for sure, but that does not prevent them from having good unscripted fights.
2) Don't expect blood or breasts destruction in any WBI video but, in the same way, you will not hear the added typical sound of punches as in JMR, DT and other fantasy productions. WBI videos are real and competitive, may be one step behind SF's or ECNWC's in aggression. As in any female fight company, sometimes the girls turned more emotional and sometimes not so much.
3) Their "Bring it Bitch" series contains their best catfights. They include hair pulling, slaps (face and bodies), body punches (bellow shoulders). Some remarkable fights are the Sarah vs Harleen's WBI314, WBI315 and WBI316. Any Bring it Bitch fight between Dragon Lily vs Jolene or Dragon Lily vs Joylyn are worth. Also their initial Bring it Bitch videos WBI014 and WBI015 featuring Jenn vs Arana (AKA Kery Spectrum) are good ones.. And finally I can mention the Ariel-x vs Dia Zerva Bring it bitch fights.
IMO, WBI has very good fights featuring beautiful, sexy and hot women but, if you want to see real blood as in UGFC, you better skip WBI.
