I personally am fine with my Dakine pack... Gets the job done. Great for park and resort shoots, but they don't really have enough room for backcountry essentials plus the ICU. It also has a rear entry system which is a must for me
My tamrac was also pretty boss. Not waterproof like the dakine, but had way more room and the compartments were laid out much better. My only gripe was it didn't have a back access compartment which for me now-a-days is a huge dealbreaker
F-stops are top of the line; biggest problem for many of us is the cost. I'm really looking into the whole ICU-mountain pack combo though. seems really smart and cheap
