Ah, you guys are scaring me now, as I have a tin of SG XX on its way right now. It kept being sold out, but I finally managed to snag one. Fortunately for me, I have this against-the-grain attitude that makes me like blends that I hear bad things about. That said, if you guys are brown rope fans and don't like it, we'll just have to see.
I have an unopened tin of the XX as well. I've not opened it because I imagine it's very similar to the GH rope. I'm interested in hearing what you think about it though. I was very disappointed with it, it's as if all the good stuff was cooked away.
