I'm picking mine up from Amain.
This is what i'm getting:
KYOW5181-55 Short Orange #55
KYOW5181-60 Short Dark Yellow #60
KYOW5183-03 Long Black #50
KYOW5183-72 Long Cobalt Blue #72
I based this off of the spring comparison chart someone posted on here last week. I just picked some that were close to the brown fronts and green/black rears I usually run. Be sure to strip the paint off so they are stealthy.
