Trade Help!! Berrian and Tim Hightower for Thomas Jones or Ryan Grant?

Should I trade Bernard Berrian and Tim Hightower for Thomas Jones or Ryan Grant? I am leaning towards getting Thomas Jones over Ryan Grant. I have AP and no solid number 2 back. Earnest Graham is injured and entering a Running Back by Commitee, And Tim Hightower is my number 2 right now. I dont need Berrian cause I have Andre Johnson, Colston, and Greg Jennings, Kevin Curtis on the bench. So basically i dont need Berrian, so it is like who is the best option, keep Hightower, Thomas Jones, or Ryan Grant. Thomas Jones has the best playoff match ups for me. what do you think??
