u sure about weight? are you saying more weight, or less weight?

i would think 2 savage shocks wouldnt even fill up a LST shock. but having 2 shocks on each arm can be a benifit, lets say your racing with one big shock on each arm, and happen to break the shaft, well your outa that race, unless your vechile can take only 3 shocks. and then lets say you have 2 shocks on each arm, and your racing, and you happen to break 1 of the 2 shocks shafts, well you still driving, and the suspension should still work, depending on your spring stiffness, and oil.
