I'm a GarGraves and Ross guy, but I'm always a little jealous of layouts done with Atlas. Much quieter because of the solid rail. Drawback with Atlas, price and maybe availability.
I'm glad to hear that you want to ditch the Fastrack. I hated it since the day it was introduced. As cheaply made as possible, and way over priced. There's almost no metal in it. You already know about the sound.
