Hi everyone, I am working on roughing out a red oak board bow and am wondering if when looking at the back of the bow it is better to have late wood  define the edges or to have some early wood for the edges.

In other words can the rough late wood grain be used as the sides of the back for a board bow can you follow the grain for dimensions.

I'm gonna use the mollgabet design so my limbs won't have a taper to the tips as in that build along

The stuff regarding grain still applies.

I'm not a novice bowyer, and understand how to select the correct grain.

I am wondering if the earlywood grain could define the edges of the limb (without taper) to prevent grain run off

or do you need some latewood on the edges to have the early rough grain centered down the limb ?

Grain orientation doesn't matter at all. All that matters is that the  grain is straight.
