One of the most interesting things I learned early on was that Orientals are a critical component in a good Latakia blend, possibly even more important than the Latakia itself. Smoke some bulk Latakia straight and you'll find it's mostly flavorless, lots of smell, not much to taste (at least that was the case with the sample I had).
On the other hand add some bulk Latakia to G.L. Pease Cairo and you have one of the best Latakia blends on the market.
Of course G.L. Pease sells a dozen blends with that done already, but it's interesting sampling the components individually.
