I know it's been said, but if minimising queing to maximise riding is your aim this is not the way to go. If you are in the park early hit whatever coaster that's open first and start from there. If you are going to that effort to get there early you'll have wasted your time if you use that quiet post rope drop period on flats that'll get a one or two cycle queue later in the day, where as the coasters will likely change from walk on to the 60 minute mark. If they open on time Colossus and Saw make the most sense as they are right together and often have painful queues.
Quantum and vortex aren't on the way to saw in any case, you'll enter the park by depth charge and the path goes from the back of the dome towards x and rush.
The park is tiny, walking by something and earning layer is not an issue at all.
