Which Fans with 10 Rib Setup

Hello evryone, this looks like a great site. I needed help in which fans to go with. I'm putting in an S-trim with a 10 rib setup on my 92. Was thinking about going with the Flex-a-lite dual fan set since it's pretty slim. but I worried about the twin 12" fans not being enough.
The car is a daily driver and I do some open tracking. I have a Ron Davis Rad, and upgraded cooling system, but I live in South Florida, so it gets HOT and humid. Please let me know what you guys are running and any pictures would be great. Thanks

I use the stock fan (for now) with my 10 rib setup. You can see a pic here. http://www.vortechpower.com/forums/s...=&threadid=214

Good luck!
