Some good references:

http://www.pacificcigar.com/eng/havana/grow/anatomy.php Pacific Cigars is the Habanos distributor for Asia/Pacific (including Canada). The info on the website appears to be lifted word-for-word (and pic-for-pic, mostly) from a small book that Habanos SA published a few years ago (that I have), which was mostly written by Simon Chase.

http://cigars.co.uk/cigar-book Hunters & Frankau, the U.K. Habanos distributor, have piled all their articles (including the Pacific Cigar website content referenced above) into their new "The Cigar Smokers Club" website. You have to register to read the articles, but it is worth it IMHO. Simon Chase is one of the true experts on Cuban cigars (okay, he's a fuggin' Cuban Cigar GOD), and he has authored a few of the articles found on the site. Unfortunately, the information is organized alphabetically in the website's "cigar book," so you have to do some browsing to find the 'good stuff.' (Look for the words "by Simon Chase" in an article's description.)

As a sample, here are Mr. Chase's top 10 regular production Habanos (no RE, LE, etc.) as of 2006:
1. RASS
2. SCdlH El Principe
3. Montecristo #2
4. Partagas Lusitania (cabinet)
5. Cuaba Divinos
6. Cohiba Siglo III
7. RyJ Short Churchill
8. Trinidad Coloniales
9. Partagas Shorts
10. Montecristo Petit Edmundos
