^^This Until you learn how to control, and move around within, an orbit, there is no use trying to get 100ton payloads into space. You can throw one of the stock 'Z-Map' Sats on the top for a little extra 'cool factor' because they don't weight much at all. But the main thing is focusing on using a small, easy to control craft. This way you can focus on learning how to control your maneuvers instead of constantly fighting with an unwieldy rocket.
