I feed my over 50 balls live. I do yearly fecal checks for parasites and I supervise feedings. If they haven't eaten it within 20 min it comes out. I've never had a serious bite, I feed weekly, and I've never had a case of parasites. But keep in mind a frozen rat can transfer parasites as well.
I think without a good start on live with you he's going to just hold out until you try it. Better to get him eating sooner rather than later.
