Our Sitka Spruce tops are in a number of grades. Seldo do we get master grade tops.( AAA or AAAAA) most are AAA though we do have a lot of AA and some single A  the single A may have water stains or some other flaw as well as wide grain .  The straightness and tightness of grain is most important, then evenness across the grain  Good vertical of about 75 to 90 degrees to the width ( quartersawn) . In Sitka the color is less an issue as it has a wide range of variation. If this matters to you Please note that when ordering .
