230 pounds? A 6.3 rear spring is way to heavy for you. I am 235 pounds and also a vert expert and I run .49's up front and a 5.9 rear. The stock valving is pretty stiff on the 2010 so a heavy spring will make it worse. Being a vet rider, I'm sure you want the ride to be a little more plush rather than getting beat up. I would also really recommend getting the rear link made by Pro Circuit or Suspension Direct (KYB). That really made a huge difference.
