Olivier, I'm glad you are looking at some of the older stuff on the forum.
I don't do rings at all. I think they are beautiful, but they aren't comfortable to juggle, regardless of how you juggle them. Everyone that juggles them complains about the pain. I am too much of a wimp to juggle them. I do whips. As long as I wear ear protection, they cause less pain and look more macho.
"A successful individual typically sets his next goal somewhat but not too much above his last achievement. In this way he steadily raises his level of aspiration." ~Kurt Lewin
