Thanks for posting. With a stamp of 33 c, I recommend the 3330 option. As you can see, this can support a window sash weight of 18 through 23 pounds. Does your window's sash fall within that range?
Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
