I wonder if the test was equal in all factors. Like scanning just one system and no more than 64 TGID's at a time. With the luxury of having multiple radios, I probably only have a max of 20 TGID's per knob position. I would wonder if the SDS100 was setup the exact same. I don't find myself missing anything on the 200, unless I am doing a larger scan or have multi-systems scanning at the same time. I guess I should say, for the way I like to listen, the G4 is the far better product for me.
