I don't seem to have a problem lifting our older ball python or cornsnake from feeding container to tank. The ball is really docile and doesn't care, but the corn get's pretty nervous after feedings. I just gently lift them up by the "lump" and support all their weight and put them back in their tank, no worse for wear. I think you shouldn't hold them for extended periods of time after feeding, but the 10 seconds it takes to put them back isn't that big of a deal in my opinion.
