I actually have a good answer for this one. Look at Daughters & Ryan. They have a variety of orientals that are very affordable and also totally respectable leaf quality. Many of them are boring to smoke on their own, but are a prime option for the home blender.
If you give it a try, I’d start around 5% as the description mentions. It surprised me that 10% was about the point where it stopped being condimental and came to dominate a blend (non-Latakia, that is).
