Murf866 is correct. The red is solid while the gold is pearl on the Rampage. It was not marketed that way back at it's release simply because the term hybrid had not been widely used in the industry at that point.
If both were kept pretty shiny their reaction may be close on the lane for any given bowler, however, if you were to keep the Rampage around 2000 abralon, for example, that would certainly smooth out it's reaction so that it would start reading the lane slightly earlier than the Swarm.
