I have the 30/39/50 with 9 speed cassette and use the middle ring 95% of the time. By the ratios 7-9 on the big ring and 1 and 2 on the small one are the only ones that don't overlap. If I see a big ole hill coming I will shift down to the small one in advance and don't worry about the cross chain. Same goes for an up coming downhill run.
