EZ track 8

[peterh]

I'm a bit interested in getting some N scale EZ track. I was thinking of building a figure eight to be used as a test track to run in new locos and also using is as a "fun track" together with my son.
I'm wondering if you could help me how much track would I need and what pieces?
I was thinking of a 19" radius.
Any help is appreciated.
