I have a spinner whose wobble is most pronounced at feeding time because she's excited about eating. It's bad enough that the safest place for the feeder is right in front of her; her strikes tend to go in random directions. As a result I only feed her f/t, and I use really long tongs as otherwise she's just as likely to hit my hand as her rat.
She isn't bad about being held but if she does happen to get nervous she'll start flinging her head, so you have to be careful to keep her away from solid objects so she can't crack herself a good one when she does. I also don't put her over my shoulders or behind my neck for the same reason; it's rather disconcerting to have her bonk her head into your nose.
Similarly I make sure anything in her tub has some give to it, in case she hits her head. So, her hide is light plastic so it slides, easily, her water bowl is a light melamine cat bowl from the dollar store, she's in a tub with sides that flex rather than a glass tank, etc.
