I use only 9. That what the Blue Ox video and the owners manual says to always use.
I can't hold on but so well. I have an arthritic thumb that doesn't allow hard gripping.

How many link did you have engaged on your chain?
I normally run 10-11 links depending on how loaded I am. With 10 links engaged I just raised the bed of the truck pretty high and the chains come right off. With 11 links engaged it will still have some tension on the bars and it will pop loose. My suggestion would be to raise the bed of your truck a little higher and hold on to the wrench, don't limp wrist it.
