I have two channel balances that I'm replacing that are stamped with just a 12 on them. One weights 8.5 and the other weights 9.5. Which option do you suggest for that weight.
Thank you,
Lloyd

I see you were looking at our S751-13. Is that the balance you have? If so, I recommend the 12R option for both windows.
