I don't know if you can get a definitive answer for SHOULD, unless you want to say "until they have reached the smoker's preferred Rh". I like my sticks between 58 and 60, so I will typically let something purchased online sit for a few months. This isn't to say I won't smoke one ROTT, or right out the B&M walk-in, but typically I carry my own when I go to a lounge. Everyone's tastes will vary.
