Champion choosing

i dont know if i should get azir or jinx. i already have twitch as an adc. i already have a hiemerdinger middle. i know both are really squishy, but azir can kepp his distance. i know that jinx can deal lots of damage but azir can stay farther back. if you say try them both out i wll be dissapointed. because aint nobody got time for daf!!!!!
