Every cigar is different. Maybe the way that it was made. Different roller and such. That's why you always try them a second or third time. I've known of a few people that hated a cigar, then liked it on their second try. Kinda like the I hate IPA's, only to realize 6 months later they love IPA's.
I won't give up on the Cohiba and I'll try it again. Honestly I've only had them on 5 occasions. 4 of them canoed. The Sales Rep for General Cigars actually gave me a 3 burner lighter even after I told him about the issues i had with them.
