My votes are:
1. Julia Stles: She couldn't beat up anybody.
2. Danielle Panabaker: Pretty but weak and soft.
3. Margo Harshman: Pretty but as weak and soft as they come.
4. Kristen Stewart: Kind of a tomboy, but gets her ass kicked everytime.
5. Holly Marie Combs: Pretty but soft gut and ass. An easy victim.
These are the weakest actresses I can think of.
