Just a note that neither case is ideal for moving around while you're shooting though. I use a 1510 and a 1610 for location lighting, and I pull it out of the trunk into a location -- and that's about it. The 1610 is even a pain (loaded) to get up and down stairs. While the 1510 is lighter, it's still not as flexible as a backpack or rolling
ThinkTank as Scubatooth recommends. From the locations, it doesn't seem like you're needing wilderness/waterproof protection. Not sure if you're dropping your gear into smaller bags when you get there, but you may have second thoughts lugging around a Pelican while you're shooting.
Or just do what I do and have a closet half full of camera bags!
