It has recently been shown that hadrons containing a single heavy quark exhibit a new flavor-spin symmetry of QCD, and that this symmetry leads to relations between operator matrix elements involving such hadrons. On examining mechanisms that might break the symmetry at large recoil, I conclude that these relations are probably valid over the full kinematic ranges available in transitions involving {ital b}{r arrow}{ital c}, {ital b}{r arrow}{ital s}, {ital b}{r arrow}{ital u}, {ital c}{r arrow}{ital s}, and {ital c}{r arrow}{ital d} currents.
