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

There is a guide in the ignition section as well about slot length in the advance cam plate, us it to set your slot length for your baseline, weld the slot on the shaft side to shorten it so you put tension on the light advance springs when they are at zero advance, you can always stretch one spring coil open like the re curve directions show (lightest one first) if you need it to advance faster.
