Oh man, I just read your post again and I'm afraid I'm going to have to disappoint on at least one level already. I only have one CC a pal gave me and it's tagged for a special occasion, TBD. I do, however, have some No 9s I'd be willing to throw in, and Caldwell is a brand I've been anxious to get my hands on!Subscribed, interested to see what you find out!
Also, you should try and do cigars that vary, like heavy dark maduros (Liga Privada No 9 or Tat reservas), some CCs, something like a Caldwell LLTK... stuff that will allow you to see how the rH affects different types of blends and wrappers.
Any other suggestions for "test subjects" are welcome!
