For the most part, getting the bark and sapwood off is best done when the wood is still wet/green. Once you have a consistent yellow stave of all heartwood, slap something over the wood to seal it. Cheapo spray shellac in a can, leftover latex paint, a quart bottle of carpenters wood blue, an 8 ft long tub of molten beeswax, whatever you can find. Put it up where air circulates and it's out of the sun. Forget it for 2 years!
As for chasing growth rings, I prefer the oldest and most cured out wood I can get my grubby paws on!
