Fahrenheit and Laff Trax have the longest lines. I would do both of those first, maybe especially Laff since it's not worth a long wait, but it's fun, whereas Fahrenheit is more worth a wait. However I haven't been there since they added Candymonium, so I don't know what the line situation is with that. But it no doubt has much better capacity, so it's probably still Fahrenheit and Laff Trax first. Then Storm Runner. Then the others. Comet is great and often has a long line, so ... hmm. I guess try to catch it when the line is shorter.
