I have long skinny hands and long fingers and have had surprisingly good luck with Specialized MEN'S gloves in size small. The finger-bits seem to be a touch longer than the women's med, and they just feel better.
For winter wear, try plain ol' wool knit gloves (very flexible and stretchable) with leather palms and finger grips. The index finger of my beloved Smartwool gloves finally fell apart last winter, so I'll be out looking for a new pair soon.
