with new a/a designs, the pressure drop is small you cant notice it. no different then air/water. no benefit to using both. unless its a track car, stick with the a/a. the a/w is nice for a track car because you can dump ice into it and since the car will only make a few passes all day long, the water will stay freezing cold. on the street, the ice will melt fast and then the water will absorb heat defeating the purpose
