I see you were looking at our S380-33. Is this your balance? If so, you can simply weigh your sash on a scale and refer to the chart we have on our S380-33 store page. This chart tells you how much weight each option can support. Once you know how heavy your sash is, just reference the chart and pick the closest matching option.
