I really prefer some blends to be crunchy to the pinch, especially some latakia blends and most Virginias. Some I like right out of the tin. Nightcap, I only smoke it so rarely that I prefer it in any form, since it tends to dry out anyways before I can finish it.
It's all personal preference. For new smokers it tends to be good to set out some general "rules" or suggestions for all aspects of the pipe. But, with experience you can decide when you want to break these "rules" or suggestions to get more flavor or just to better your experience. Try it in all forms and compare. However, if you are a one pipe a day guy this may just be a year long daunting task, ha ha, since you'll take forever to get through a tin.
For me when I smoke a very dry blends, I almost don't draw or puff on the pipe at all. I just let it smolder into my mouth on its own in a good, open pipe. This is just my preferred clenching style. How you want your tobacco should just compliment you style. I find that moisture adds to the tongue discomforts and
sometimes detracts from the flavor, most of the time.
Can it get too dry? Yes. Loosing water content is one thing, but when you've lost essential oils in the tobacco, it definitely kills the flavors and even the nicotine :::shivers::: Don't waste precious nicotine!!! Ha ha!
There are no real hard fast rules to anything about the pipe. There are lots of antiquated suggestions that have become like rules and even mythologies. But, for the most part, no one is going to cancel your pipe card or punish you for breaking them. Hell, breaking rules is what makes this thing fun :
: YMMV
Happy smokes!!
