Yeah the few smokes I've had have been straight, I didn't really think anything of it until I read a negative review on 4noggins. They replied with 'Gee I hope you didn't smoke this straight, it's purely a mixer etc'. I'm going to have to take a crack at mixing in some Burley one day.
Otherwise it's a fine smoke on its own, the Vinegar smell doesn't translate as strongly to the smoke in my opinion - but it all depends on personal preference as well.
On a sidenote, I accidentally spilled some on my carpet and decided to vacuum it up with the Dyson..
Talk about a heavenly smell everytime I used it, up until it was eventually emptied
Maybe it's worth stoving ?
