Whilst the belly split has thicker rings, they look like they have a lot of pithy pores through the heartwood. This is usually a good indicator that the wood is low density. The rings from the top stave are narrower but they don't look like they have the same amount of pithy pores in the heartwood.
I suspect the top stave will make a stronger, lower set bow than the same design, and dimension bow from the inner stave.
You could make the lower stave a bit longer or wider, and lessen set.
