LOL!
If you think Athearn trucks roll poorly, you never tried Bachmann Amfleet trucks (original and new versions).
But unless you removed all the yellowish lubricant from Kato Amfleet trucks, they will not roll anywhere as good as Kato's standard outside bearing (pointy axle ends) trucks (unless you filled those bearing cups with automotive axle grease). Yes, I compared them too.
Well, if Rapido used the same design as they did in the Comet cars, then don't hold your breath.
Oh man, I had totally purged the Bachmann Amfleets from my memory. Those things rolled like pyramids.
Kato's inside-bearing trucks may not be as free-rolling as their outside-bearing counterparts, they're still far from "render a normal-length commuter train un-pullable by a single locomotive" bad. The same can't be said for the competition.
