Stanwell Melange (which someone mentioned already) made me sneeze, yes, sneeze, for hours! What the hell is that all about??? Worst tobacco ever.
Also, and I know I'll get flak for this, Squadron Leader tastes like (what I imagine) the sweaty socks of a drill sargeant would taste like. Horrible stuff. And I love English blends! LOVE Latakia!
Actually, I've had a few SG tobaccos and they've all been pretty disappointing. Maybe I just need to try some more, but I can understand how the original poster would be scared away from an entire brand.
