are super incubators worth it?
If you have 9 7km eggs in regular incubators you can hatch them once and replace them. Total == 18 eggs. If you have 9 7km in super incubators they need 4.7km each; you can hatch them, get 9 more, hatch them, and then get 9 more. ... For me, super incubators are not worth more than regular ones.
