Will these be two ply or one? Also wonder if the track will be flat inside were the idlers run, or will it have the ramps to make quiet?

I was curious too, I looked at tracks USA and it looks like the 137's are 2 ply

I can't say on the 137", but I have heard 2 ply for the 129" at least that is what has been reported for the El Tigre.
