I'm lrating this a "5" based on a local standard, not compared to Whistler or Colorado or Utah, etc. I really think this is one of the absolute best trails in all of DFW. I normally only ride the Lone Wolf section, so this review will focus on that portion of trail. There are several rocky climbs that are really a challenge. If you aren't in great climbing shape, or if your tech climbing skills aren't sharp, you will really be huffing and puffing. However, these climbs come with their reward, and the downhill flows really well. This trail is a lot of fun, and there are a couple sections where you can really pick up some speed. I like the few jumps (all optional) that are interspersed, and there are a few berms to help maintain flow.
This trail is rocky in sections, and it is often dry. That means there is typically a "loose over hardpack" trail condition going on, especially on the first half of lone wolf, which works well with some tires and not with others. This is very apparent on the dam drop section of trail, where there are a couple somewhat sharp turns with a gravel layer over hard dirt. It's a blast, but I'd advise caution on your first go-round.
This is a really great trail, and I'm glad to have it within a reasonable distance from my house.
Northshore and Big Cedar are probably the trails closest to Sansom in terms of difficulty.
