I don't know if any cob could be considered a high grade pipe, but these seem to be at the top of cobs to some degree. I know that Dave Neeb carries some Ricco Santia Cobs that are a whole world of better. But I came across this on ebay and it caught my eye. I wasn't looking for a cob but I kinda liked the looks of this, and it had a lucite stem. Seller said smoked very little, and it looks it. It's a MM customized by Custom Corn Cobs. Priced about 1/3 of what they cost new, I decided to bid, and no one else did. I guess it's a Diplomat 5th Ave. done up in orange with a nicely figured matching lucite stem, that I guess is something like the forever stems. It's the biggest cob I have now, and will give it a whirl this afternoon to see how it smokes. ::
