Draggin,
Do you have the pipe welded to a plate on top where it is bolted to the truss. What I'm looking at in the pictures indicates you don't have anything to control the side to side wobble. The tracts need to be stable both vertically and horizontally. One bolt top and one bolt bottom...
I use the mesh mat from Harbor Freight. Your tools do stick to it a bit but it doesn't bunch up, it's cheap, and in the two years I've been using it it doesn't react with oil on the tools or any other chemical I've exposed it to. I have some Sears stuff in another box and prefer the HF stuff...
