I've had good and not so good leaf from both sources. I think that they end up sometimes with leaf that the big buyers reject.
Whole Leaf does have Prilep and Latakia, and I just got some good looking Virginia Lemon from them. Their Izmir, is shipped too dry, and I ended up with a lot of crumbs, because they ship in a plastic bag. Doh! Ask them to ship in a box.
Leaf Only has Yenedji, and it's lovely stuff. On the other hand, their Light Fired shipped too wet and had mold. When I complained, they told me that all tobacco has mold.
Hopefully, a more robust whole leaf vendor will set up shop, these two are in need of competition.
