Have any of you guys used the ball weights with the allen screw that brings the two sides together? Lots of guys who advocate them say that the user should wear them all day to get the most benefit of long stretching sessions.... Check out this guy's video as an example... AustinGemini
I think they look cool, and I'm sure the weight (especially the big ones) really does give a monster tug, but being 'locked in there' makes me a bit nervous about getting caught in the wrong situation and not being able to make a quick graceful exit (so to speak).
Anyone worn one of those out in public and had it discovered, or unexpectedly seen when you didn't expect it?
