We are using a timing belt. I don't know about the advantages of disadvantages of going with timing belt over cable, but we felt like trying a timing belt system because we made a cable system in 2005. The timing belt system is designed such that the motor can pull it down also. Because of needle-bearing pulleys and precise machining of the mast there is very less friction involved so gravity does do some of our work in bringing the elevator down. Surgical tubing was used to keep the gripper from swaying left and right violently during a match.
