I hiked it (and kept hiking for another 5 days). So Whatever I brought I had to carry with me for a week basically. Do it as early as you can otherwise the line will sort of ruin the fun of the final run up the dome. As I recall I took a 5d classic (5dmk2 didnt exist yet), 24-70L, and a 70-300IS. Based on gear I own now I\'d brought a 17-40 and maybe one telephoto. I wouldnt bother with a full size tripod. Don\'t underestimate how much 3500ft (or whatever it is exactly) elevation gain means to your legs, and lower o2 content at 8k.
