I split all my wood, you want the moisture to escape through the sides as opposed to the ends.
With splitting it is possible that some pieces will twist or run out, but that is a chance I always take. having faith that the wood will do what it is meant to do.
With splitting you are assured the wood will have continuious fibres and it is neat to watch how it will flow around knots, not possible with sawing.
Then seal the ends and wait.
The smaller you split the faster it will season, so I like to get down as close to final bow dimensions as possible, because I use only handtools.
6" trees usually split into quarters and the last tree I found which was 12" diameter got split into beautiful eighths.
good luck.
may the force be with yew.
