Between a camera backpack or roller bag, my first choice would be a Roller. It's an easy way to carry equipment without stressing out your back and shoulders. The problem is that these rollers are difficult to work with when navigating through very crowded events (like CES), so a backpack ends up being the better choice.
There are many events to attend this year, and so for those reasons we decided to look for Hybrid Camera Bags (see a list of bags considered here) that offer the best of both worlds, and that's how we ended up with the Tamrac 5797 Evolution Speed Roller Backpack.
At just under $380 dollars, it's one of the more expensive bags on our list, but we needing something durable. When traveling for several days, dealing with something as simple as a broken zipper could be all the difference. From reviewing several other products, the Tamrac 5797 Evolution Speed Roller Backpack was the best one we felt was built to last, provided the convenience of a roller, while offering the best comfort as a backpack.
There is plenty of room for a few camera bodies, several lenses, audio equipment, misc accessories, and a full sized Macbook Pro Laptop. The Tamrac 5797 Evolution Speed Roller Backpack is still sized to carry on a plane so you don't have to check your gear when you fly.
