Depends on who I am riding with and the terrain. I go up hills 2-3mph slower on the bent, so if I am riding with a group of faster riders or on a very hilly course I ride the DF, otherwise I ride the bent. Works out to about 50-60% bent, 40-50% DF. I switch hit on rides alone, partly to avoid DF deconditioning, which never the less has occurred, especially in the saddle.
