Yep, Pierre, that's the hill! It is smooth and grippy. I love listening to the sound my wheels make when I'm skating it.
Martin, the Bahne Rockers are 31". The DH guys will do well, however the first eighth of the course requires quite a bit of pumping to build speed.
Here are some pics:

The start...wide gates. double/triple pump to build speed.

First turn...still double and triple pumping.

Straightaway...swooping, full road width carves.

The big right...the course takes you from the far outside left, into the apex, then back out again.

Finish chute...you finish in the right lane. Notice the uphill runout.
