When people started talking about Tambolaka, it was because there were rumors that it was on it's way out. If memory serves. I believe that some said that there was no point in trying something that they would most likely never get an opportunity to buy again. I was one that didn't get a chance to try it, but I'm not heart broken. I've been blessed with being able to try a ton of stuff that is hard to get, so... Anyways, another unique one is Cotton Boll Twist. A very, very strong rustica based twist, made in small batches in the US. Good stuff, if you've got the cajoles to stomach it.
