Back when I was the maintenance person for the Strads in the Henry Ford museum, they asked me whether they should lend them out or not. I told them that I could not decide that for them, because it depended on their priorities. If they wanted to best preserve them, they should not lend them out, since this will inevitably result in wear, and occasional accidental damage beyond wear.
