Just for fun I have come up with my own RBO route. I don't plan on making a run, but I think if anyone wants to try they should use this route. It is different than Saturn's because it choses to fight crocomire, while his route is a no mini boss route. I think that the grapple beam would save maridia from being a boring piece of crap to watch. The crocomire energy tank also eliminates the need to return to brinstar after collecting the speed booster.
