Despite  popular belief, the design of the valve when fitted correctly is such that no amount of boost can ever force it open, so the spring is really there just to help it close quickly.

Green spring is fine, yellow if you feel the need to change it 

Run a shim in the valve too, sealed in with some silicon, it greatly reduced the chamber volume making it faster to react.

The vacuum on my 008 forever pulled the valve with a green open. And a yellow made the compressor flutter on occasion. Plus it was too loud which the girlfriend hated!

OEM 710n works flawlessly
