I have been using Atlas #80 track, but as switches go bad I have replaced them with Peco switches. If I were starting out, I’d use Peco track. But not #55. Too many problems reported with wheels hitting the spikes, unless you want to change to Fox Valley wheels. I have to look closely to tell the difference between 80 and 55 anyway, so appearance is not an issue for me.
I personally don’t like the Woodland Scenics roadbed. I prefer the cork. I had a much harder time making it look nice. That’s just me though. I’m sure many people love it.
I used it on my first layout, and it looks rather nice. Besides, I already have a good deal of it. And to shape, you only need a pair of scissors.
