Doc, thanks for the pointer to Carey's DF#7, a new one to me. I did some hunting, read reviews and found their website. It is now added to my list.
Referring to your earlier post regarding Tom Palmer of Peterson Pipes, I would be careful of accepting what he says as gospel regards Peterson tobacco though I don't doubt he means well. As far as I understand it Peterson Pipes and Peterson Tobacco are two entirely different companies and as such might not be so willing to share sensitive information. That said I think we both agree SF and IF (as currently produced) are excellent smokes.
Regards,
Jay.
