 
The original Robot core gave us the big backending 718A while the Modified Robot core gave us our strong rolling 716T, so we knew it was a great core. For this new release, we modified the densities once again to create a strong continuous motion at the backend of the lane. This new version is the Modified Robot 2.0.
