If you're getting a bounce as the ball comes down the inlane onto the flipper, the bottom of the return lane isn't level with the surface of the flipper rubber. If you loosen the screws securing the ball guide, there's some play in it, and you should be able to adjust it so it doesn't "hop" when coming down the return lane.
I agree, that if the ball hops when it hits the flipper after coming down the return lane, the game is not playable.
It definitely does depend on the game though, whether red or black is appropriate.
I've got red flipper rubber on my TZ (and it plays much better than black rubber) and black rubber on my No Fear - and, while I havn't tried reds on it, I don't think i'd want the flipper rubber to be bouncier on that machine - it sends the ball screaming at the flippers a lot - fast enough that even with black rubbers that bouncing it off the flipper sometimes causes it to bounce high enough that it hits the opposite slingshot (usually not hard enough to trigger it, thankfully).
