+2 I've had a couple and I decided to immediately slap on some Public Enemy "Don't Believe the Hype." I don't understand how these got the rave reviews that they did and I think they are one of the worst DE products put out to date. However, having said that I also think that they have great aging potential and I am sincerely hoping they end up like the cigar.com prerelease. I'd take one of those any day of the week over the released version, no question.+1 have had 4/5 13's and i personally dont like them. i hope they do age into something or i'll be bombing out this box!I don't think the UF-4 and the UF-13 are at all similar. I can take or leave the 13, I'd walk through hell in a gasoline suit for more UF-4s. That said, the 13 will age, I think, into something special. Also, that said, I'd trade a sealed box if 13s for 4s any day of the week.
