Hi,

I have 31" balances that I have figured out are s385, but I am unsure of the weight option. They are stamped with

If you are certain about the Series (and we recommend that you carefully check both ends of the balance), then your stamp of "30 3" indicates you will need a "3030" stamp option on your S385-31. Please double check before placing an order.
