Opening That New Tin

Okay guys, I need your feedback. Sometimes when I open a tin, the first bowl is great and then things decline thereafter. After opening other tins, the first bowl is somewhat underwhelming but the tin improves with time. Other tins smoke great from the beginning to the last drop.
What is your ritual or procedure when opening a new tin of tobacco to obtain the best results?
Do you take off the lid and let it "air"? How long?
What do you mean when you say you "rest" your tobacco?
Do you have different procedures with different tobaccos?
Do you rub-out an entire tin of broken flake when opening and return it to the tin?
Do you leave tobacco in the opened tin or transfer it immediately to mason jars?
I am curious what you successful veterans do.

Thanks guys for your responses!
I normally smoke 2-3 bowls per day, six days a week so I don't smoke up tobacco very quickly. If I pop a 50 gram tin, I leave it in the tin until it is smoked-up. If I pop a 100 gram tin, I transfer half of it to a mason jar and smoke-up the remainder.
I am more like Roth in that I usually prepare or dry my tobacco one bowl at a time. I have had to rethink this technique with McClelland Dark Star, which is really high maintenance in my book. I took a hint from a reviewer after getting a real poor quality (1 sour note) smoke on the second bowl. He suggested rubbing out the entire tin and placing it on wax paper for two days to dry before transferring it to mason jars for 2-3 days to "rest". I was desperate so I gave his method a try. Since I live in a low humidity climate, 24 hours was ample. The results were great. Go figure. Maybe I would have gotten the same results if I had let the tobacco "rest" in the tin for several months. I don't know, but his technique worked.
I think there are no right answers here. It is important to be able to size-up an individual tobacco and try another technique if your initial results are poor. Patience, and possibly experimentation, is the cornerstone of this hobby!
