Antur is great fun, it is a bit more flowy now they have sanitised it a bit. Taking the rock drop out of the red was probably a good move as it could be a real surprise if you hit it on the right hand side.
If lift assisted I tend to wear as much armour as I possess, am on dh bike and going at about 90-95% and antur is pointy if you come off.
Just have fun and take it slow on the first few runs.
The only challenge on the blacks there is line choice, some lines are very definitely better than others
