Wow so many responses cool I feel you should definitely use both but I also feel theres no point in looking at a composite chart if the synastry chart is bad. I also would like to know what Sun square Sun in a synastry chart turns into a composite chart. I went out with this one girl I really liked and the biggest hugest value aspect we had together was sun square sun in the synastry chart but with a composite chart i know its diffrent or it changed to something else. I wonder is there a table of synastry aspects that show what they are in composite aspects.
