Hi there BusterHymes!
When I hang BTC, I normally lay my back on my bed, lay my legs on a chair right in front of the bed, leaving my pubic region “in the air” this way the weight falls right down. I use a 13lb barbell, I wrap an “electrical wire” around the handle, making a kind of very tight attachment place were only the hook of the bib hanger fits. This way the only length between the weight and the hanger is the strip with the hook that comes with the Bib Hanger. This leaves me a pretty good ground clearence. If you hang seated I guess that maybe the way I use the weight can help also.
Also, do you use weight plates? I guess so, so you can probably try to use a big piece of electrical wire, or skinny wrope or whatever, and wrap “both sides” of the plate, making a “bridge” on top of the hole, where you atach the hook.
Hope this helps!
PEace,
