Yes, they are two quite different weaves.
The first pic below is an electron microscope pic of the radial fabric. You can see there are extra fibers in the 0-axis direction. The loads on the radial panels
would be lined up with these extra fibers. I don't have a similar pic of regular hydranet but the second pic is a portrayal of that weave which you can see is balanced between the 0 and 90 degree directions.
