To achieve this, we left room for the hooks anywhere along the length of the robot within about a 1 foot span. To locate our COG we stood the robot up on its frame with a wheel on each side between the table and the frame and rolled it forward and back until the bot remained level without us supporting it. The location of the COG is directly above the line segment between the contact points of the 2 wheels on the robot frame. This allowed us to locate the hooks such that the robot would lift level.

It looks like you have some play with where you can mount the hooks, so perhaps this will help make your robot lift without much swing.
