I run Gorden bars in England in wheat, barley and canola, they are certainly better than the speciality bars. Just had to weld a small block of steel on the rotor front to balance to within about an ounce. A friend told me to use a broken magnet from a flashing light etc and stick nuts and bolts to it untill it runs nice, then weigh them and cut some metal the same weight and weld it into the same place.
