You should be able to use either the red or blue tipped S600-21 balance. What is the weight of your window sash? To determine the weight, you can simply remove the sash from the window and weigh it on a bathroom scale.
Submit a couple photos of your balance boot so that I can help you determine which replacement part you need to order.
