I like the Kuba Kuba, Ltd. Def Sea (CI only I think), Acid 5 (Kuba Kuba on crack), and Cold Infusion Tea.
If you go to Cigars International's site, then to the "Make Me An Offer" section you can get Kuba Kuba's for a good price. They won't pull up if you search "kuba kuba", "acid" or even "drew estate". To find them look at the big "filter bar" on the left. Click "popular", then after the results refresh click on "10 packs". Kuba Kubas are usually burried a page or two deep in those results. I have routinely had bids of
$40 for 10 accepted. You might be able to find a price lower than that. If you do let me know!
Also, if you like Acids, try out Drew Estate's Natural line of cigars. They're not infused like the acids (unlike what some think... Think about it... the name is "Natural" for a reason). My favorite out of them is the Irish Hops. Very smooth and mellow.
Finally, as a detective, sherlockholms, I'm surprised you haven't found the Newbie Sampler Trade.
http://www.cigarasylum.com/vb/showthread.php?t=46087 Jump in and start trading! You most likely won't get acids, but you'll get some sticks you surely haven't tried before!
Hope you enjoy!
