Yorkie... On the Team Orion site they have a range of springs which are listed in degrees.... the wider, the stronger... much easier then remembering colours...
WIth Trinity... I only know green is softer than red which is softer than purple, the hardest I will go except for the one cam with my BRM....
From what I have gathered.... the tighter the spring, you get less RPM but more torque... but either too light or hard you will get more comm wear....Light springs = more bounce and hard springs = more grind!!! can't win.....
