I know, you've read this kind of question a million times in different forums, and there's never any right answer. Nevertheless, having myself read and laughed at these kinds of questions, here goes:
I'm going to be travelling for nearly a month in the Greek islands and Tuscany!! It's primarily a family trip, and it's the first time we're travelling w our 1.5 yr old son. So I thought of just taking the Hasselblad kit and the Bessa for people pics. BUT, (big but), I have several hundred sheets of quality 4x5 film in my fridge, a very light Gowland 4x5 kit, and a reasonably flexible, patient, and reasonable wife. My parents are joining us for the first half of the trip, so there'll be someone else to watch our son. What would you do? (that's the kicker).
