Well, except that I havent called any retailer for the springs to see how they are sold? We definitely NOW have a thread with as much information on front springs, for Gasgas Pro Aluminum Marzoochi forks as I know, hehehee!

Just to be a total PITA - your total equivalent K for the forks would be .66 for two .33 springs.

Two springs exert twice the force of a single spring right?

Here is another example. Kawasakis new motocrossers this year brag about lightening the forks by going to one fork spring.To get the correct overall rate for one spring in one leg they would have to double the spring rate that was used in two fork legs with two springs.If they used two .50 springs in two legs last year then to get the equivalent spring rate they would have to use a 1.0 spring in one side to end up the same.
