GrandSlam45 gave you the answer on the red being the best to start.
There are various videos on how to do the exercise, but this is definitely a good one:
Tennis Elbow: Step-By-Step Instructions For Treating Elbow Pain Using A Flexbar (Tyler Twist) http://www.youtube.com/watch?v=A2QQaVfeI4U
The twisting action of the Flexbars are meant to take advantage of the fact that all the muscles of the forearm, that run from the elbow and across the wrist and into the hand, run in a diagonal.
It makes sense then, that twisting the flexbar, and twisting these muscles, leads to a "better" strengthening exercise.
While there are other ways of getting supination and pronation of the forearm by using a dumbbell (or even a hammer), the best study seemed to indicate good results from using the Flexbars.
The idea in rehab is to start with a fairly gentle motion to keep the muscles moving while new protein is being made to repair the microscopic tendon/muscle tears involved in "tennis elbow".
So the red Flexbar is designed to "gently" exercise the muscles, but not disrupt the healing that has already taken place.
If you can do the "Tyler Twist" with the red for a few weeks, it is time to move up to the green Flexbar.
By then, the areas healing should be strong enough to tolerate the added stress of the stiffer green bar.
Any return of pain means the healing tissues are being pulled apart, and time must be given for more healing to occur.
It sounds like you are a very good player.
As such, you are a victim of your own success.
Even though you are undoubtedly fairly strong from all your ball bashing, that also means your forearms are taking a lot of abuse from being the last muscles along the kinetic chain to absorb the impact from striking the ball.
Stronger muscles, which are more elastic than non-elastic tendons and ligaments, should help prevent a recurrence of tennis elbow.
Returning to tennis is less likely to result in an early recurrence by returning with soft (multifilament or gut) strings, and a fairly flexible frame.
Some find that they eventually can try a hybrid - this is probably a better bet than trying to get back to a full poly set up.
