I have recently purchased a (D.R.) Cohiba Robusto and smoked it last night. It was the variety that had the yellow band and I really enjoyed it. This was my first ever Cohiba. I have been shopping around on the internet and have noticed the yellow bands and the red dots. My questions are; what is the difference between the two different types. Why the big difference in the price and which ones are the better smokes? Your opinions are appreciated.
