I agree with the smoother shifting. When I went from a 50/36 to 50/34 began dropping the chain occasionally. I have a truvativ crank and went with FSA chain rings and had to install small spacers on the rings per a recommendation to improve the drop chain ratio. I guess the FSA rings are slightly more offset than the truvativ rings.
