What's your favourite gear ratio?

I had a dream last night that I changed my gear ratio to 48/17 and was immediately able to do supercoolwicked skidz. That was the entire dream.

It's bullshit though because i'm already riding 48/17 and I can do barely average skids on a wet day.

Doesn't skidding slow down or eventually bring your bike to a standstill; why would you want to do that?
