Weird burn line or normal?

[fiddlegrin]

I agree with the above. If you will rotate the slow side downward when you draw it will likely catch up.

What?! On what planet?

I've always put the slow side (side with unburned leaf/filler/wrapper) to the top.
the theory is that;
Heat rises, so it will then encourage the combustion of the laggard side. I have always experienced this to be true.
I have also always experienced that doing the opposite move will exacerbate the problem.

Sounds like we need a poll...
