I'm not much of a mod guy, but the aftermarket orb dome thingie was a little too large for my taste. On the pro, its really hard to see the orb dome lit up when it is flashing from underneath, since there is no newton ball for it to reflect the light. Solution for me, steal the blue dome from the right side of the playfield, bore out the appropriate size hole on the plastic, and flip the dome to the top, just like the dome to the left in the pic. You can do this yourself if you are brave enough to modify the plastic. Just make sure you protect the LED board from underneath since it will be exposed. Meaning you don't want the ball to be able to hit the LED board. I used another clear plastic underneath, but you can use just about anything.
