I definitely wouldnt classify the trails at Uwharrie as fast because they are 2 way and there is lots of traffic. A place like NCMP has what I would call fast trails because they are 1 way and you can actually go fast without having to worry about hitting a truck or other rider.
Its a fun place to ride but I can cover every trail at Uwharrie in about 2 hours, so it gets boring unless Im in a truck. I think it would be more fun on a UTE since you would be riding slower.
