Correct channel balance for sash weight

A quick learner from Florida says:
I have a 23 inch balance with a number 2230 off a sash that weighs 17.2 pounds and a 17 inch balance with a number 1620 off a sash that weighs 9.2 pounds. Since these are close to the maximum weight allowed, should I order the the 2230 and 1620 or should I order the next size 2240 and 1630.

Thank you for your time.

I would stay with the 2230 stamp for your 17.2 pound sash and 1620 for the 9.2 pound sash. Your sash weights are falling in the middle of these stamp weights and going any higher may negatively impact how the windows function.
