While I haven't had that particular RG, the El Rey del Mundo Panatelas Largas I've been lucky to smoke a few of. Same size, also '80's vintage. Phenomenal smokes. There are two boxes in Mo's upcoming auction that I might be bidding on.
As for the PSD#5 above, I haven't had tight draws on any of mine. It's an okay cigar...would I prefer a great D#4 over it? Yes.
