I ordered some SS Ball Bearings from Amazon over three years ago. Depending on how much dry hops I use I could use one or both. This last batch I had 4oz of dry hops (cones) going in and used both. When I went to rack the keg the bag was completely soaked which leads me to believe there were no issues sinking it once all the cones soaked up some beer. I went this route b/c I didn't think the threads on the nuts and bolts would be very good if I didn't clean them well enough, too many small hard to see areas on them.
I also have the tubes as others have posted. They work well with pellets and sink nicely, but if you are using whole cone hops they do not hold very much once they expand. They work well if you want to dry hop in the keg too!
Good luck and cheers!
