While I was talking with Thomas from Davidoff Geneva(oldest Davidoff shop ) , he told me higher rh% will give better aroma and more subtle notes and he said 6-8 weeks are needed for cigars to acclitimase humidity. And I learned that Zino Davidoff was selling Cubans and other cigars at 72 rh%. He said less rh% will more spicy and linear smoke but less burn problem.
On the other hand JJ Fox (225 years old shop ) keeps their cigars at 65 rh and 65 F. They said better experience at 65 rh and 65 F.
I will experience those. It is matter of personal taste. And after talking with a lot of people, I saw that there is no magic or correct number. There is 60-75 rh% range for cigars and you should go which you like. The only thing is 6-8 weeks is needed for cigars to acclitimase humidity and than you can smoke.
