Using two stock light springs in distributor advance, good idea?

So ya'll would say leave the factory springs in there? I say this because I have an after market camshaft, 4bbl carb, headers, and high stall converter. I've been reading about having full mechanical advance in by about 2,500 RPM and that ordering the Mr. Gasket springs and only switching the heavy one out is the way to achieve this. I just was wondering if the same could be achieved by using the light spring from the old distributor.
