Twister is appropriately named. Not a straight line to be found on the trail, and that's the joy of this ride. You will likely rub some shoulders on trees if you aren't picking your lines carefully, as there are a lot of skinny sections with small trees. But everything is easily navigable if you're paying attention. There are a few hazards, but nothing advanced. Some roots, a few short rocky sections, and an occasional felled (small) tree on the path.
There are a lot of turns. You'll never stop turning. Some turns are bermed and let you maintain your speed. Others require a little finesse to roll through at higher speeds. Overall, it's plenty fast and offers very little to slow you down. The roller hills near the beginning feel great, and don't require much effort to get them started. Visibility is good for the climbs, and only once (I think) was I dumped off a hill to speed into a fast turn that wasn't bermed. So there was a section or two that I had to brake where I would rather have maintained some speed. That could just be my inexperience, but the braking felt inopportune once or twice, if that makes sense.
It's mid-fall, so the trail was fairly littered with pine straw in some places, but the trail was very visible, and only a few sections were covered. This isn't a flat ride, but there didn't appear to be any challenging elevation changes either. This trail nears the Back Door red trail into the Vortex free ride area about 2 miles in. You can see it on your left, via a large rocky hillside and a gate. Walk across to Back Door, follow it left (southish) to the freeride area and go left past the dirt jumps for a fast route back to the Vortex trailhead. This area of Back Door has no challenging features. Just a few roots and rocks.
Twister is a flowing ride with lots of turn, lots of skinnys, and one low-clearance felled tree that I had to duck under (nice feature). You will enjoy it!
