I've still never been to a Chin event anywhere, but I hear good things about them and I might hit them up the next time it aligns with my schedule (which won't be the TWS one you mention unfortunately!). The TWS Performance Driving School is run locally by the TWS staff, and it's an incredible value in terms of track time per dollar, and doesn't tend to have wait lists usually (although I'd still sign up a few weeks ahead if you can just in case). I plan to be at the one you mentioned in late Sept.
Driver's Edge also runs DE events there and I think they're really top-notch, especially when it comes to focusing on driver education in the lower two rungroups (Green->Blue). However, they open their events for registration 2 months in advance of each event and sell out those lower two rungroups within an hour. Yellow/Red don't sell out as fast, but both of those rungroups demand some significant prior track experience. Yellow/Red is still currently open for their Sep 6-7 event at TWS, but Green/Blue is sold out. They're doing another TWS event Nov 22-23, but if you want to get in before it sells out on Green/Blue you have to hit the signup page at 9AM Monday Sept 22nd (
