I had them custom made by a customer (mfg. of floor mats and car covers) I printed brochures for. We tried 28oz 38oz and 48oz carpet material and the 38oz (no deadener) seemed to fit down in the groove the best as I recall. I have seen fancier (more bling) but none that are any cleaner or fit any better. I posted pics back in '06 .... I'll see if I can find them.
