I made the move to full frame a few years ago, and I no longer have anything less than 24MP (outside of my phone). But for a long time now my emphasis has been on the glass. The difference that you get using fast glass is astounding. Until you get the 70-200 2.8 for a while, I am not sure you will understand me, but when you do, there is no going back. You will no longer be satisfied with the rest, seriously. I could almost buy a new X for the cost of my glass. The Think Tank series of bags is like armour for your photo stuff, so that has my vote, but good to see what you guys are using.
