Black magic spring rates?

[shrike]

I bought some Black magic springs off ebay but the specs listed for the secondarys are not in lbs. so I dont know how they compare to arctic springs.
Would anyone happen to have a black magic spring rate chart?
I understand they soldout and I have been unable to find anything on line, any help would be greatly appreciated.

I also bought a set of black magic springs too and am wondering the same thing. If anyone can help it would be greatly appreciated.
thanks

I never would have guessed that information on springs (driven for me) from Black Magic would be so hard to come by...
Guess I'll have to get a fish scale and do it like the demonstation in Olav Aanes clutch tuning book.
