What metal wheelset replacement works best with MicroTrains Heavyweights?

[MarcVanCleven]

You're right on the money, Nate! Converted my entire Great Northern 1929 Empire Builder, and it ran great! Unfortunately, I had to convert my cars back to the original MTL couplers. I tried the MTL True-Scale Couplers which was a very easy conversion. However, N-Trak modules vary too much, and the couplers wouldn't stay together.  So I'm contemplating going to Z-scale couplers.

I use the Z scale couplers on all my heavyweights.  Haven't tried running them on an n-trak layout, but they work fine on the modutrak layout and at home.  I do find that I need to give them a little "grip" so I paint them a rusty brown color.  They tend to stay together better.

Good luck.
