Ok, I tried this again tonight.
My homemade Bib, attached VERY close to the head gives me the least skin stretch, so I used it for this test.
First, I attached and hung 5 min. normal BTC to allow things to settle. Then I tried various reverse OTS styles for a few minutes each.
I only felt a better stretch than regular BTC when the strap was running straight up my crack. This wasn’t comfortable on my tail bone, nor my balls. I put the strap both BTB and to the side of my nuts. BTB felt slightly better, but still uncomfortable.
To get around the nut issue I tried running the strap over the side of my butt (in the groove between hamstring and glute). Not a good stretch for me. It has to go directly up the crack to rival or exceed normal BTC.
My conclusion: If your nuts can take it, and you prefer to stand while you hang, try reverse OTS. Take the strap right up your crack. Maybe add some padding on your tailbone if needed. Otherwise, fuck it. Stick to plain BTC in a chair. Much less hassle, and easier on the balls.
That said, we are all different. What doesn’t work for me may be fine for someone else. :)
