These Elites do seem to be a difference compound as they all have this light orange tinge to them. Not the same formula as Insane-A-Thane. They do come in either the EZ-edge or Hardline shapes so shape/contact patch size could have effect on speed. Wider surface would be slower but stable.
Raybourn 54mm are Hardline shape
WIDTH 33.42
ROAD SURFACE 20.2
Long Break 54mm are EZ-edge shape
WIDTH 33
ROAD SURFACE 16.5
Does Ron Whaley write these things?
"Elite WAY TOO FAST Urethane is here! Flying out the lab to the streets and beyond, Elite Urethane guarantees more speed, a longer lasting roll, and more importantly hands down epic times with your crew. If you're a skateboarder, you seek more speed. If you want more speed you're gonna f$ck with Elite.
Ben Raybourn's Elite pro wheel comes on OJ's Hard-Line all terrain skate park shape. Hard-Line features a tight radius and a conical edge that creates a wider riding surface for increased flat-spot resistance and slide control."
