Re: what causes the scratchy throat on exhale?
I know exactly what you mean.
I've had this problem with Nakhla and I actually solved it just 2 days ago.
Do you pack your tobacco under the rim so it doesn't touch the foil?
If yes, then try to pack the tobacco so that it does touch the foil and poke only a coupl big holes in it. I use 2 quarters of Exoticas and there is no scratching at all anymore.
If you wanna know more, send me a PM or just write me on here or something...
