Yes, JimInks and Pipestud are my go-tos on tobaccoreviews.com.
Our taste isn't always the same, and they often detect things I don't, but once I got an idea of our relative tastes, it was very easy to get a good idea of whether or not I'd like a blend from their reviews.
Also, if you get a feel for forum members who have similar tastes to you, that's nice. I've noticed several forum members who had similar tastes to mine, so if they like a blend, I know chances are I may as well.
Tobacco is an interesting product to buy over the internet, as you can research all you want, but it still is a plunge into the unknown and you never really know what you're going to get!
