Rubber net is a good way to move rays...plastic bags are even better, but your more likely to get nailed that way. Do what your comfortable with. Don't risk it if your not comfortable getting in close proximity of your rays. Netting a ray stresses it out big time, but they recover quickly.
Excellent point. A good pair of angling gloves is a great idea as well. You never know when you might have to catch a ray for some reason like a net breaking...
