I was also there on Saturday and I agree that it was awesome. Though the 8:20 start time sucked, it did mean that we didn't have to wait at all for any of the obstacles.
Monkey bars and rings were what killed me, so I'll ensure that my grip strength is up to par for next spring!
What happened with the 15 jump? The only difficulty I could see is if you're afraid of heights. The high berlin walls also didn't happen for me, I cramped up in places I didn't know I had.
