Good reasoning, I agree. I don't think the thickness would be an issue either, unless your in an area with alot of black sand. Providing the slurry is exposed to the mats surface it should function fine.Tathradj said:The closed back mats are around 5 mil thick.
I prefer a closed back mat as it stops the heavies working their way
along under it.
If gold drops in the closed back matting. It stays there.
