I will not, from experience agree with Barney's comment, 700 lbs will remove the same weight off the FA, no matter the rig! I changed out a set of 6400 lb springs, for 8400 on an older SW 3500 I had, amount removed from FA dropped 100+ lbs with higher capacity springs! This was with 1500 lbs of HW mind you!
650-700 lbs of HW on same truck with 6400 lb springs, removed a whopping 60-80 lbs. So the formula to get amount removed is not linear as some say. Rear spring capacity, soft or firmer springs will effect how much is removed from front axle. The more you squat, the more weight is removed. Hence why trucks are usually asset high.
Not sure if a dual cam is still around, I like the one I have for my TT long since ad. I will agree, an all in one is better.
