I've never seen it move unless some digs it up. How does it move with 4" +rock on top??

I've saw it move with 12" on top.

Some think fabric stabilizes everything. It does not.

I think we all know that. Point is, where in the name "304" does it indicate what size that screen is?

304 stone meets the requirements from the odot specifications, also known as b19 to old guys in Ohio. B19 is old spec number for 304

I guess your saying in sank in 12" deeper? Was it the 12.5ft wide rolls? I've never seen that happen but if the fabric went down that much, rock would have only pushed in deeper without it.

Just got back from a town meeting where the local town is re-doing a large playground. The area around the swings and playground equipment was stripped of overburden a foot or so down to hard clay, geotextile fabric put down, and then some compacted crusher on the fabric followed by half a foot of C33 playground sand.

The first rain storm turned it into a pond. Holds water very well.

Well, sounds like they dug a hole into non draining soil, and put sand in the hole. Yes, that would stay wet if there isn't swales, slopes, or pipes to convey the water.

In my area I'd take 4" of aggregate with fabric under it vs 8" without it. I know people that have been adding gravel to their driveways every few years for the the last 30. Rock sink in and dirt pushes up.

That's a vicious cycle fabric or not ... you add weight to one area then it sink and the side lift up... fabric only help avoiding the mud making its way through the gravel up to the surface...

And, again, where in your description does it tell the layman what size the stone is?

The fabric going down isn't the problem. Problem is the soil below the fabric percolating and pushing the fabric to the top in spots. Then the maintenance equipment grabs it and yanks it out of the roadbed. Good times.

There was a good translation in some thread here on TBN recently. I remember it made interesting reading about all the different callouts for size and type of fill material. Regional differences in the ways stone & crusher runs are called out. Maybe someone remembers.

And lets not forget the inventor:
