Unfortunately, I believe you will need to stay with the channel type window balance, since you have aluminum double hung windows. You can't make this kind of window a tilt-in or incorporate a jamb liner.

Manufacturers don't really make "better quality" balances as opposed to "low quality" balances. You really just have to work with what they design for your window. That said, the average life expectancy of a window balance is approximately 10-15 years, depending on use.
