No, we set the saddle height based on the bottom of the stroke, but we choose a crank length based on the top of the stroke - because that's what effects the angle of bend in the knee. So if the knee bend you get at the top with 165s is best for you, and the knee bends too much with 170s, it will be the same with taller pedals - 170 will still be too long, by the exact same amount.
