Track

[johnv6]

Is there a difference in Peco and atlas flex track, and can you intermix the to brand's? I am still having trouble trying to decide on code 83 or 100 track.
I know the layout I want to do and I'm going to need about 100 pieces of flex track that's a lot of track to buy and I don't want to buy the wrong one. I'm sure you know what I mean so HELP HELP!! Please.

I use Atlas(Walther's flex is made by Atlas, if I'm not mistaken) Code 100. Cheaper meaning I can lay more of it. I also use Walthers switches. I think that they are made by Shinohara.
