or 
are both good viable options on him. (again i haven't tried these myself but i do know his kit and he really wants mana and early ap. 
is also good to use as you can press it mid air right to boost damage once you know the enemies are going to get hit by it... or save it is you know you missed your ulti or the damage wouldn't kill them.
flag and drag that can can still use it while rooted.
