Fall recruitment at Vandy is more informal than spring and is for older girls because freshmen are not eligible until spring. I am not extremely familiar with Vandy's fall recruitment structure, but be aware that at some schools, not all chapters participate in informal recruitment. For instance, AOPi only lists dates for spring formal recruitment on their chapter site, while AXO lists dates for rounds in November as well as in the spring. If you go through fall recruitment, you may not have as many chapters to choose from as you would in the spring.
You mentioned that you have friends in AXO, so that is a great jumping off point... it's a lot easier to rush as an upperclassman if you know people. But be aware that since you will be going through recruitment as a junior, it's important to maximize your options and look at all 10 chapters, not just 2 or 3.
