Hey PB,
I make nearly all my bows from quartersawn boards. I use Northern Michigan (local) woods and have made self bows from Wht oak, red oak, ash, black ash, black walnut, hard maple, red elm. My favorites are the walnut,red Elm, maple, and both ash's. 2 others that I have not tried as of yet are Blasck Locust, and Hornbeam ( both are supposed to be very good also.)
Just my experience though
