If I find a cigar that is especially great, I keep the band and write "crib notes" on the back of it.
The bands go into a box I have and at a later time, if I need to remember what it was, I can generally find the band from the cigar.
If I write down the name of a cigar in a book, I just confuse myself. Having the band, gives me a visual referance.
Sometimes, the band is too small to write anything on though, like the Monte #2. So, I just write YUM. LOL!
