I don't think the Rolling Thunder has changed. I know at first everyone thought the new version was so difficult, but I don't believe there is much difference.
Every competitor was chalking, except me. I was wiping the chalk off with a towel I brought before I would lift. I hate chalk on the device, or on my hands with RT. There are a few of us that way, but not many. I was going every lift: 171 left, 182 left, 193 fail left lift right, 204 fail (not too far off of all the way up). I think it was the same device as the previous year, but it "felt" better this time. And that is the way it went for Haugen this time as well. I say "humidity" has a huge impact as to performance, as well as the individual's person hydration. Some people think I am nuts for saying that, but I am convinced it is a big factor.
