Looks like a 2 bow stave to me, warbow or not. There is a fine line between greedy and wasteful with yew. Taking a stave that could easily make two bows and only getting one could be considered wasteful. But it is your stave and you can turn it over in your hands, and look down the back, and touch it and caress it a little...while we just look at your pics. I like Del's suggestion. Lay out the best bow, and if your offcuts can make something, then great.
