If you want more "stability" or a more snappy feeling, we recommend the gold 25lbf springs sold as accessories. The different springs don't change the turning radius, nor board lean, but they do change board stability and response. These trucks come fully tightened for maximum stability, but you can back-off the kingpin by one half to one full turn to make the trucks respond to your preference. If you're a lighter rider, you may want to loosen the kingpins to allow you to get that flowing sensation.
