Fulcrum hanging?

I’ve been having trouble hanging more than 10 pounds with any of my hangers. I have a few homemade ones and my MB Vaccuhanger. I like the vaccuhanger the best, but at higher weights it really kills my glans and tesnds to slide off after a while. I tried something different today and was able to hang 20# for about 5 minutes without any trouble. I put on my vaccuhanger as normal and hung the weight from the center of my shaft and held the head up with my right hand. I got a great stretch, better than anything before. Has anyone else tried this out. I am going to look into it further.
