SS Spring Rear Shock Combo, What to use???

I realize Dusted's needs were more for launch than ride quality, but for us that want SS Springs that will see A LOT more street use guy's have suggested using C-Body Rear Shocks.

Can anyone back this up? Seems like a great option.

Would this C-Body shock be the way to go for SS Springs on the Street?

(haha the application says 'for towing and hauling' :-D)

Might need to put the springs on 1st and measure the distance between the mounts to make sure they fit ok. ????? max and min travel?????
I don't see any measurements on these.
