don't have much choice around here for mud sill, and borate treated Douglas fir is fine for this, as long as it's covered and remains dry. SPF, (Spruce, Pine, Fir} is grown so rapidly it is sponge wood, I would not use it for building anything.. Especially, after I'd hand picked choice, dense, solid, nearly clear, #1 grade, sticks of SPF, used in plates above CCA in an old house which I couldn't complete, but let a "friend" stay in for free, provided he maintain it. He let the roof leak for a year, It did not hurt the older woods, not in the least, nor CCA, but the SPF, disintegrated....
Unfortunately due to the dangerous qualities of CCA, it's no longer available except for special uses.
