Sorry this is sketchy but here goes.
In my Unilite, I ran 24 initial, 38 total in by 2600. Very snappy.
I know I ran one purple spring but can't remember the other. I'd guess it was the natural steel spring.
You can try those springs then test with timing light and run up to 3000 to see where it stops. If you have a compression lower than 10.5, use less initial.
Best I can do...
