Wilmikitivic devoe,
It's all with technique, and time spent with a particular device. I'm uncut and hung up to 20 pounds with a bib for a long time. With my MaX-Vac it took several months to learn exactly how to use it. I read your above post, consider the amount of time it took to hang heavy with the bib. I got guys hanging 15+ pounds for 5 hours straight, just a month after NEVER vacuum hanging. That's not correct either. It should be taken slow, especially when initially starting to hang and with any device it takes months of consistent use to master. Even "the guy" that hangs for 5 hours straight has not mastered the hanger. It took me at least 6 months to really understand whats going on. But... 10 pounds in the bib for 30 minutes made my cock look like a shriveled marvel. Weird colors, and it would shrink from fear after a session. I can hang for a long long time now. Post session indicators are very positive. I can easily reach fatigue with 10 pounds after an hour straight session. I will put up some images of a 50 pound hang soon. If anyone else attempts, I will fly out and kick your ass, personally.
