I'm really happy with my 50/34 X 12-30 set up. From memory, I think I use the top six gears with the big ring, and the bottom five with the small ring. Pretty minimal crossover with that set up. The low 34X30 takes me just about anywhere I need to go, but the 50X12 pretty much never gets used. I should actually move to a 48T or even 45T big ring.
