Buy fewer larger capacity cards? I'm looking to add about 16gigs of memory cards for my dslr and m4/3. Do you guys recommend 4x4gb or 2x8gb cards? It'll be about the same price and I know it may be generally better to buy lower capacity to spread your photos out so you don't loose too many photos should a card crap out. Oh another thing, for those who have both a dslr and m4/3, would you carry both for a trip overseas or just one? If just one, which one would you take?
