Whats everyone running for gears?

I originally posted 3.91 in my Dart but opted instead for a set of 3.23 I had as well.
We like to take lots of weekend getaways and when I calculated that the Dart on 24.5 inch tires with the 3.91 at 75 mph on the interstate would be around 4000 rpm, I changed them to 3.23's.
