this is a really great wood,,looks like you sawed kerfs for the splits,,which I dont recommend,,even on the worlds straightest tree If you saw kerfs, there will be slight grain violations,,now If you band saw the the staves in two,, there will be more grain violation,,thats two chances now for problems,,,,If you split now you will find out how straight the grain is,,because your split will follow the grain which now may not line up with your outside edges,, probably best now to let the mosture stabalize then band saw in half and hope for the best,,,,mike
