When you say your hoops are weighted, do you mean they have water or sand in them? If so, that could be one of the issues you're having. My favorite hoops have the same weight at each of the 360 degrees of the circle. Hoops that are weighted with water or sand are always creating a cross current of pull against you and don't distribute the weight evenly throughout the hoop. If you look at rhythmic gymnasts or jugglers or anyone who balances a hoop, you'll see that they never weight them. It throws off the balance. It's possible that your issue is that, which would be good to know as far as correcting it goes.

If you do have water in your hoop and you ever decide you don't want it in there anymore, it's easy to fix. Just drill a hole in the hoop and then place it, upside down, in your bathtub. The water will all drain out and then you'll have a balanced hoop again. Sand, though, is harder to drain.

But if your hands are parrallel instead of up and down, that could totally be the issue too. I'm glad that you've had that epiphany and I hope it helps you. I look forward to hearing about your progress as you move forward.
