Weird burn line or normal?

[Laynard]

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...

I'm with Old Smokey. The oxygen on the lower side (top side suffocated with smoke) encourages combustion. Poll is needed indeed.

Yup, I used to think the same way as fiddlegrin but read on here you put the slow side down instead of up and it works. Would make for a good poll. But those that vote to have to slow side up would be wrong.
