Start with the online retailers' posts on individual blends. SP does good specs on nearly every blend they sell. They give a lot of info on strength, constituent tobaccos, and usually the little pitch that goes with the blend actually contains some information. Then check out reviews and find the reviewers who are information rich. jiminks is often the mother lode for that. Finally, simply do a carefully titled original post on Forums with the specifics you still want, giving the information you already have. Someone on here often has real inside information on specific blends. Good luck.
