Sorry, I misunderstood. I thought you were referring to these long double ended female couplings as something that everyone had and that most were replacing their push connectors with these. Since this Crane was just released I assumed that it couldn't be this coupling that was becoming a staple in enthusiasts collections.
As far as the new chassis with the wheels affixed to the axles, I actually think they roll better with no side to side wobble.
