Personally i would choose just the basic binding, mount it in a suitable position for the skis use.
The Schizo would be usefully if you wanted to change the mount position on the skis. As they allow you to move the binding up and down on the Schizo mount. I would suggest the normal binding, save the cash.
If you want to put the binding on a ski that you would like to ski in many different areas and snow types, like an all mountain ski, then you might go for the sliding ones so that you could set them back for softer snow and pow, and then move up closer to center for park.
