Kalista help

I am trying to learn kalista, to use in ranked, I can do ok with her. (I don't feed, but i'm not the hyper carry I should be)

My main problem comes in mid-late game team fights, when you have crazy attack speed, and have to control your hops perfectly.

Does anyone have any tips or tricks for mastering kalista's passive? Do you use attack move, or right click to attack? Right now I use attack click, unless I am fighting in a wave of minions. But I have the hotkey assigned to a mouse button, and mess up my jumps when trying to use items as well.

Any help would be much appreciated :)
