I am stilling learning how to take the advantage of this suspension bar which has three rings and is three feet long. I purchased this recently. I definitely see the use case. It is less restrictive then a single ring and the bar can rotate. So it does not have the limitation of the bamboo with only one direction. This is a beautiful pose by @jenni.art.model / @jenni.art.model.2 . The up-line spacing is different from a single ring and bamboo.
