Think for me it may boil down to cost. Which I can't seem to find yet.

What I learned last night is that part c is all the ingredients normally found in there own salt buckets, less the salt.

Isn't that still balanced?
They only question that remains is if you believe that TM part a, b are of better purity then bulk.

That's what I am trying to decide
