Best positions on a sex swing?

I used to have a swing (I left it with an ex-he kept the swing, I took the bed straps). I wasn't too crazy about it as we always seemed to have trouble finding a the right momentum. My favorite position was doggy style, as the swing could hold my weight, he could hold the straps, and I would still have enough leverage with my legs and feet to push back. Good luck and I hope you find more pleasure out of it than I did.
