I have been feeding the entire tank.  I stopped target feeding quite sometime ago. All of my corals look very healthy to me, but I am always wanting to see improvement.  Do you target feed your corals? if so what types do you feed? I have felt that my tank provides enough food to sustain itself, so I never really spot feed
Why are DT's better? I honestly am not happy with marine snow and would like to try DT, but I want some feedback first. 
Thanks for your input, 
Meklo
