Not familiar with the Think Tank, but I recently got the LowePro Pro Roller X200. Love it as a roller case that's carry on friendly. Haven't had the opportunity to try it as a back pack for an extended period, but it looks like it may not be the most comfortable hiking pack.
If I'm going to go slogging around for a full day, I'll probably take my Tamrac Expedition 7x along also, and transfer whatever gear I need into that.
I looked at both of these bags in the "quote" and decided to go with the LowePro Pro Roller X200. It seemed to be a much more durable bag for air travel and honestly you can put more gear in it. It has held up well during my travels. I bet you can get all your gear listed in the bag easy. I can put my 1D-X, 16-35, 24-70, 70-200 and the 800 in it + the Speedlight. The 800 is a monster and almost takes up 1/2 the bag. The bag weighs a ton but rolls very easy, great wheels on the bag. Only drawback is if you travel out of the country this bag does not meet the "Europe/Asia" size requirements for carryon. The bag is a little too big. I avoid the issue by traveling on US airlines (Delta, United, American, etc.) When I go overseas because their domestic carryon rules are a little more liberal and allow this bag in the overhead where European carriers will not. I admit I have not used the back pack portion because I usually take a smaller bag for my gear in my checked luggage and use that when I reach my destination. I'm one of those bad people according to my wife that will sacrifice clothes for camera gear.
