You had indicated that you will be using balsa will a plywood doubler.
I would overlap the splice point so the splice of the balsa, and plywood are not at the same location. This will give you maximum bonding area. This in effect is laminating wood together which yields a stronger construction than a single piece of wood.
Thanks for the note, Six Shooter. In this case, the ply doubler only covers the wing cutout. I wanted to keep the balsa splice somewhere on that doubler, but I'm thinking of moving it forward as indicated in my reply to Brian above. I'll use another ply double under the splice.
