I'm not a fan of flavored cigars, as they tend to take away from tasting the tobacco properly. I think they add the flavor to mask the cheap leaf they make them with.
On the other hand, I've had a few of the CAO flavors and they're not as bad as I first thought. I agree with the above as the Moontrance is quite good actually.
I picked up a tin of the Bella Vanilla cigarillos to keep around for folks that aren't "into" the whole cigar thing without being left out, and I fired one up a couple of weeks ago. I liked it, but I won't be smoking another. It just didn't do anything for me.
