Troy TRX rail - shape?

[HeavyDuty]

I'm having a hell of a time finding an end shot of a Troy TRX quadrail to see how oval (or not) it is. Can anyone describe the cross-section?

they are round I believe

I played with a couple today and they were round except for the top rail.

I also didn't think I would like them. Wow was I wrong.

So the left and right rails are the same distance from the centerline as are the top and bottom rails, ala YHM or MI?

Bumping for more comments... to reiterate, I'm asking about the TRX quadrails, not the round TRX Extreme rail.
