I agree about the weight in the front Schwintek Slides, the Schwintek Slides work pretty good on a light weight slide but the more weight on them, the more problems / issues.
Our last 5er had the Schwintek Slide system on a large Kitchen / Entertainment Center Slide and it always made noises opening and closing and struggled to operate.
