tip color for spiral balance

A quick learner from Pflugerville, TX says:
Replacing a 3/8" diameter, 29" long series 306 spiral balance. It is really old so it does not have a colored tip on it. The other balance is still working and can almost hold the window by itself, the window slowly creeps back down. What color tip should I get?

Hello! I'm not sure. I recommend weighing your sash on a scale and telling me what you get. From there, I can recommend the best tip color option for your balance.
