In addition to what Nick and Jason said, I almost always want to stay E of the DL, and if it's a "classic" set-up, just a little S of the triple-point. I know I'm going to want to be SE, E, or S of any meso, and that ought to put me in position right from initiation.
Rule number 1 for me is: Never, never sit under a stratus deck. Find the dry slot and get there.
Always factor anticipated storm motion, and not just from models or soundings. If they say NNE storm motion, but storms fire near the TP, and there is a significant CF draped E-W to the E of TP, you're most likely going to get storms that ride the E-W WF/CF bdry. If that happens to be, say, near Scottsbluff, you may have a big (no) road-network problem, and you might just want to play a different strategy for the day entirely.
I will also factor in the threat that forecast storms pose to people. Everything else being equal, I will chase storms that threaten, say, AMA, as opposed to storms further up into the PH, so that I can get reports to the NWSFO. Yeah, even though there's gonna be 1000 other chasers on that storm.
There are areas where I will absolutely never chase again, such as anywhere S of I-40 and E of I-35 in OK. Jungle.
