Bamboo TK

Great harness, worked great for several models. Can this harness be used for a face-up suspension? With different hip harness, of course.

I really enjoy this tie and the aesthetics of the bamboo. My bottom really likes the bamboo for its load distribution. We have tied this tie at least 12 times in lab sessions, partials, and full suspension. Has anyone experienced any nerve issues with this tie? During our last full suspension my bottom experienced nerve impingement to her axillary nerve resulting in skin numbness across the regimental patch area of her shoulder. We feel that the impingement occurred under the overlap of the ropes in the upper wraps, which act as a spreader. I think this occurred because the combination of my upper wrap being a little bit high, sitting over the deltoid, and the overlap in the rope was too close to the armpit. This type of nerve impingement is difficult because the bottom doesn’t know it’s occurring. As a top, I know that the axillary nerve emerges from the brachial plexus in that area, but not that it was at risk of impingement from the top wrap. I believe that the overlap in the top wrap/spreader rope provides a pressure point that isn’t present in continuous top wraps without overlaps, and that a lower placement of the top wrap/spreader in the bamboo TK harness is therefore much more crucial because of the overlap which sits near the axillary nerve.

I've tried this on several people and found that loading it from the bamboo tends to pull the arms back to an unsustainable level. I've rewatched the video a few times and feel like her tension is about the same as mine. I oddly tried to load this from the top wraps as an experiment and had various different bottoms tell me it was much more sustainable. I also tried loading both top wrap and bamboo and found it still pulled the arms back quite a bit. Anyone have any thoughts on how Gestalta loads this vs. your experience loading it?
