Oyamel Firs are where many Monarch Butterflies Migrate to in Mexico. Millions of them. The forest is protected. But there are Oyamels in other areas used for furniture and such. I don't want it for top wood. Just to incorporate it into the guitar somehow
Look at the grain on the side of your braces. See how it runs at an angle?
If you were to split one of those braces it will split right along the grain at a tangent to the bottom of the brace. Ideally, the grain needs to run perfectly parallel to its length. When you split the billet before cutting it to size that ensures that runout is at a minimum.

The side grain will ideally look

You can't see runout from looking at the end grain or the face of the board. What the endgrain does show you is whether the grain is cut on the quarter, or whether it's rift or flat sawn. But runout is as important a factor in the strength of the brace as it is being quartersawn.
