WLT is the site sponsor for Fairtradetobacco.com, which is a forum primarily about home growing tobacco, rolling cigars, and blending your own pipe tobacco. Great forum with friendly members always willing to help you out if you are having difficulties with something. Also, the sponsor is very hands off within the forum which is nice.
The pipe blending sub-forum has been fairly active lately, so if that is what you are interested in I recommend checking them out regardless on where you make your purchase from. I've been having a lot of fun making home blends myself based on recipes posted there.
I have ordered from both several times. I have been impressed by the quality of leaf from both suppliers, and they do not seem to have much overlap in cigar varieties, so if you are looking for a specific leaf, then only one or the other typically caries it. Seem to have similar pipe tobacco selections. However, WLT just got a supply of Turkish Basma that members are raving about. Have fun!
