Positive Rear End On The Street?

[derf <derf247@gmail.com>]

Making a rear positive by welding in wedges seems easy enough.
Spridget chunks are cheap, too.
Does anyone have experience running positive rears on the street?
Could one expect fewer broken axle shafts with positive setups?
Or, more broken axle shafts?
Why?

I had planned to just go standard but if there is a slight advantage
to be had, I would try the positive setup.
