My two favorite designs for locust are either a stiff-handled flatbow about 66"-67" long, 1 5/8"-1 3/4" wide fades to midlimb tapering to 3/8" nocks, or a Cherokee/Eastern Woodlands design about the same length, slightly bending handle, 1 1/4" wide to a bit past midlimb tapering to about 5/8" nocks.
