I've been thinking some lately about what makes a trail "technical". I take the term to mean requiring some learned technique above and beyond just sitting on the seat and pedaling. In that sense, almost any singletrack where I would be technical to some degree or another. Trails are pretty tame where I live, but one still must deal with sudden ups and downs, twisty sections, sand pits, the occasional root. One at least needs to be able to weight shift on the bike, maybe lighten the front wheel to get over downed branches, apply the front brake on steep downhills, and don't those things qualify as "technical" skills?
