How much does your 8x10 weigh? Is 11 pounds reasonable? I don't plan on going on long hikes, but would like to hike a little with my cameras. FWIW, I'm very active and relatively fit, but am not a big woman (5'8" and 115 lbs). Still assessing the 8x10 vs 5x7 thing! Thanks for putting up with my ignorant questions!
