Handguards and heated grips are probably the most versatile set-up. I have the Oxfords, and Acerbis Multiplo's with the big 'touring' deflectors. Comfortable down to ~40* with plain leather 'sport' gloves, and the heaters on ~50%. I can survive my 30-min commute down in to the ~20*'s with this setup and regular gloves, but by that point, i've usually switched to insulated gloves.
