I guess that as long as you don't put too many points in the area-effect increase, you can have a good charge. I don't think it good to wait for the passives, so I'd probably just rush and insert points into the weaker grenades for any of my pirates (which is what I did with Dog).

The Stink Pot already has a decent area-effect at one or more points without the other skill of which I speak.
