The webbing straps in general make it difficult to turn the rings in and out since that rotation puts twists in the strap, which try to shorten the strap, requiring lift. For a 1" wide strap, the twist is minor and doesn't have much of an effect, but with a 2" strap like on the Rogue Rings, it's noticeable and annoying.
Competitive gymnastics rings eliminate this by using a swivel anchor.
And thank you for your comments on the racks. They're getting better (aesthetically) too the more I build, though there isn't much way to improve on the strength.
And yes, I'm actually holding that handstand. Get on my level.
