It's good to mention about having good electrical connections in the track.
The one thing that I look for is how well does it fit together if you do a custom track plan? Well I can say that Fastrack fails greatly in this department as it needs small fitter pieces to do what I use to do with tubular track in 042 and Fastrack don't always stay together for me. I had it on a floor layout, not fastened down.
A little FYI, I am still using a postwar ZW transformer that I bought in the 1960's, replaced the rollers once or twice and cleaned the contact area.
