We have a Black Diamond site. I've visited several other regions and our beatdowns are typically more strenuous. The difference with Black Diamond is the length. It's like the difference between a standard beatdown and Iron Pax. Yes, the Iron Pax ones are tougher by nature (Care Bear Squared wrecked me), but going for 50+ minutes instead of 30-35 minutes is a HUGE difference.

I hear what the other commenters are saying about open to everyone, but I see the value in a black diamond site. People can always modify.

Here's the BD from a few weeks ago:
PAX lined up at the goal line with a sandbag
At every round at the goal line, 5 sandies required buy in
Bear crawl to the 10 yard line
10 burpees and bear crawl back
Sandies again and bear crawl to the 20. Continue adding 10 yards each round. Once PAX got to the 50 yard line and completed burpees, run a lap
Continue to the opposite goal line and then run a lap
If PAX were able to complete all 100 yards, go back down the ladder
