30A esc will give your ESC's some more room to breath. it'll have a less chance of burning up. Especially if you like to go full throttle! I use 30A esc for 20A Motors.

What about ESC ? I think those may be OK but are 20A enough or are 30A really necessary ?http://www.banggood.com/SimonK-10A20A30A-ESC-With-BEC-For-RC-Aircraft-p-924336.html
