I also have a Time Warp with "Banana" flippers. That's the way I played it back in the arcade days, so I have left them that way - I did try out the game with "normal" flippers but it wasn't as fun IMO.
Just this game and Disco Fever had them.
Here's the text of an email by The King Steve Ritchie with his recollections of the background to them -
