With 4.1 all ratings increasing our white damage (hit, haste, crit, expertise) will become slightly more interesting (+40% dmg). And most if not all nonset pieces have haste, too.
helmet: cho'gall and t11 both have haste on it. Unless you're willing to use maloriaks (exp/mastery) one with a stamina socket bonus instead of eg 30 strength on t11..
chest: atramedes and t11 both have haste on it.
gloves: t11 and chimaeron both have haste, elementium is a low strength version (tank)
panties: elementium got haste
leaves you with shoulders from halfus
