Roller bag suggestions

I'm In the market for a roller bag to hold my 6D and 7D both with grips and gear in my signature. I am leaning towards the Think Tank Airport Takeoff due to the versatility of it converting to a back pack. Anyone use this bag? Pro's or con's... Also any other recommendations on other bags.

Thanks in advance for any help

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 have the airport International which is the same size without the backpack option. For me I would not want to carry it as a backpack as loaded it would be very heavy. Just depends on how much gear you are going to put in it. Great bag, I have 5 TT bags and love them all.

I love the TT Airport Security. Right now for basketball I carry it and a Retro 50 ontop of it, and the wheels have saved my back many a time. I thankfully only needed the backpack converstion once and at 60+ pounds with ramp and elevator closed, it works but was not fun. It really comes down to the size you want. Think ahead, the bags are expensive enough I think of them as long term investment not nessicarly just a means to carry what I have now but what I'll be hauling in 3-4 years. I've dug through all the TT bags at the camera shop, the attention to the details is there across the board.

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.

My plan when traveling outside US is to carry on the back pack insert, which should fit fine into the int'l overheads, and put other items like a jacket or other items i don't need on the plane into the roller shell and check it. The insert is basically the same size as my Expedition and I had no problem with that traveling through Europe last year.
