In pine though ? Unless you're pulling stock out of the firewood
pile, most pines ought to be pretty straight. My money would still be
on some moisture issue,

I'm also puzzled by this heartwood/sapwood split - IMHE, pines don't
have a strong distinction here and they don't go around splitting down
it. This might be a diameter thing related to the drying. What
species was it ?
