>Sure, though a hanger has some limitations such as only partial length subjected to stretch,<
That doesn’t really happen at least with a bib hanger or an AFB the majority of the weight appears to be transferred to the lower edge of the hanger, so in reality you are probably stretching from a point just behind the glans.
>limited time under tension,<
Very true. It’s very much a brute force method and I think people ramping up weight too quickly are probably also creating scar tissue easily.
>and negative effects from extreme compression levels.<
Yeah, I’ve never managed to attach a hanger in such a manner that the compression is as low as with my hand.
>I see the hanger as something for the senior part of a PE career, though many people will be tempted to get one too early because it has proven results. Even Bib didn’t start with a Bib device<
I’m with you on that, I don’t think people should go to hangers until they’ve exhausted manual methods. For some people manual methids just don’t work though (whether that’s toughness of tissue or lack of technique is another question I guess).
