Steven,

Keeping the rod in tension rather than compression is a good idea, but you should actually do the bending calculations before ruling out pushing with a cylinder. Most cylindars are designed so that their rods can handle max force the cylindar can produce in compression. Rods are typically destroyed by side loads.

Also cylinders usually have more push force than pull force due to the area taken up by the rod.
