Anyone replaced their Schwintek slide with a pulley system?

The cable systems are no better than the Schwintek.

I have spoke with four different dealers around the country and they told me to replace the shcwintek with the pulley system. Could you please let me know if you know someone with an engineering background that could help me with my problem. The repairmen I have contacted refuse to work on the schwintec and they told me that they are under engineered.
