ok, if the black spring is light, then it's the weakest spring you have. If the silver is medium, the it's kinda stiff, and if gold is heavy, it's the strongest spring.
The lighter your spring, the less fps you will get, or if you have a LP setup, it will get you shooting within the field limits again.
If you need more power, go heavier. I reccomend you just going to your local pro-shop with a chrono and have them help you out if you don't have a chrono yourself.
So, why did you buy a spring kit?
