Sorry about that.
You are 100% correct. I would argue though that Visionary is still using the React A Tack covers (or very familial versions) which is what was the base for the AMB Centaurs covers.
I don't know physics well enough, but you would think or want to believe that a ball with a greater diff to start has the potential to end with a greater diff than balls with lower diffs. I would think that it is tougher to get the dynamics out of a static core compared to a hopped up monster, like the Guru core, the Jackal core, etc.
