I'm #3.
I guess I just like the variety. But like Embers or Bob, I go through phases too. Sometimes I'll go from one blend to the next, as if I'm a noob again, on a mission to smoke as many blends as possible. Other times, I'll land on a blend and stay there fixedly (so far this summer, Sutliff 507-C VA Slices has been pretty close to that). I've tried to detect a pattern, but there doesn't appear to be one. It's just random, changing with the direction of the wind seemingly. The only times I can count on trying blend after blend is when I receive samples, but that's understandable.
The idea of having a fixed rotation seems almost counterintuitive to me. If I wouldn't have a fixed rotation of music to listen to, why would I apply this concept to tobacco blends? ?
