I think rockets are a safer and more dependable form of harass vs most ap mage mids, who can be a lot more mobile while farming, keep good distance, and aren't really disrupted by the blind from grenade (but still get 1 rank in grenade early so you have the full stun).

But other than mid vs AP mages, I agree... DEFINITELY go with grenade first if you are up against any AD, melee, or attack-based champion in mid, are top vs any physical or melee champ (which is almost always), or are in bottom lane.
