Flippers, yes. Very predictable bounce, decent grip, plays like classic rubber except lasts longer and doesn't disintegrate and leave extra dirt on the playfield.
Slingshots, maybe. I can't tell any difference in bounce, but it's nice that they last longer.
Posts and rings and everything else, eh. If I need to change these I'll put Titans on, particularly in spots that take a lot of wear, but it's not a top priority.
