| Brian,
I'm of the opinion that from the middle to the outside is the best way.
As you move away from the centre the gas velocity drops considerably. Due to this when you are using the centre part of the scrubber you have a reaction front that moves faster and a deeper depth of "reacting" lime. as you get to the outside this reaction front moves slower and reacts over a much shallower depth.
From this I would also summise that whilst a radial scrubber makes more efficient use of the lime, a partial breakthrough will escelate in severity much faster than on a convential axial or co-axial scrubber.

I should have hit refresh, Padowan has described what i was trying to say in a far more eloquent manner.
