Caster recommendation for lifted Ex?

[jbhebert]

I'm going to be extending my radius arms and building new mounts as part of the buildup on my '94 XLT. From searching the forums, it appears that the stock caster spec on these trucks is 3.2 to 5.2 degrees. I'm going to shoot for this range once the truck is lifted. Has anyone found that the truck runs better with more or (I doubt) less caster when lifted?

Thanks in advance.
