Manual Steering - Standard vs Fast Ratio?

I have a 16:1 Flaming River box in my Duster. It's awesome at speed, go-cart like almost. But it's a bear at parking lot speeds. Definitely don't want to do much turning if you're standing still or below ~5 mph, parallel parking isn't much fun. I have 225/60/15's on the Duster right now, so not even all that wide a tire. The 16:1 is a pretty big difference in effort vs a 24:1. Fewer turns, but a lot more effort.

I have a 20:1 for my Challenger when I convert it to manual, but I haven't tested it out yet. Unfortunately the 20:1 isn't easy to find, it was a replacement worm gear offered by Mopar Performance and I don't believe they're being made anymore.
