My coach did fit the bike to me overall. I don't honestly remember if she set the length of the aeros or not... the end I cut off was the end sticking out towards my body when on the bike (as opposed to the end you grasp) - and thus giving me the willies about poking myself on them... so she may have set them up, then I marked them, took them off and lopped them off.... though I may have done the lopping before I had the fitting too. Can't remember. The way they are designed they are still adjustable. I just cut off most of the obvious excess.
