Is your commute mostly or only partly on a trail? If it's mostly on city streets, it's likely that it won't matter what you do; the limiting factor is probably traffic signals. My 4mi/6.5k commute takes me 19-22 minutes every day whether I ride my Tarmac or my old Rock Hopper with semi-knobbies. It's the stop lights.
