Like JR, I have no experience with that species, and I DO think that matters. I work primarily in Eastern White Pine and Douglas Fir. In fir, we prefer FOHC (free of heart center), and in pine, we prefer boxed heart, becuare the two species behave differently as they dry. In general, the fir will check less and shrink more in dimension. The Pine will shrink less dimensionally, but instead will open up larger checks. By using boxed heart for the pine, these checks won't penetrate all the way through the timber. In fir, the dimensional shrinkage will tear apart a boxed heart timber, as the center doesn't dry as fast. This will lead to a really big check on at least one face, and creating a... somewhat non-rectangular cross section. You'll need to find out how your species behaves. I'd start with a local sawyer, if you don't get any advice here. CB.
