I'd prefer the term "valets" for female managers like Trish, but then again, I'm a little old school. Nothing would beat for me the good ol' days of Bobby Heenan, Jim Cornette and Jimmy Hart. You won't find any better managers than these 3.
As for valets, the list is a little shorter but impressive nonetheless: Miss Elizabeth, Missy Hyatt, Baby Doll, maybe even Woman.
