Green Tips are not often used for 5/8" diameter balances. Can you confirm that you don't have a 3/8" diameter balance instead?
If you are certain your balance is 5/8", then I recommend weighing your sash on a scale. You can then cross-reference its weight to the chart we have on the S600-33 store page to determine which is best. |
