I dont have the deflection for the 2512 but I do have them for the 2215's and the 2413's

2215 deflection is .343 76lb spine
2413 deflection is .305 87-88lb spine

there is a formula to figure the deflections out...got it stuck on the tip of my tounge..will post it when I can spit it out <img src=icon_smile_wink.gif border=0 align=middle>!
