I dont work for servo city, but they have great info and FTC approved parts on thier website...
Here is the specs on the standard servo:

You might consider upgrading the servo to a quarter scale servo which is newly legal for 2013-2014 which will give you a significant increase in torque:

Another option is gearing the servo:

Also something that helps using servos are servo blocks that take the sideload off the servo horn (a common breaking point for servos):
