My Pro Pac is holding up extremely well,after winning it in one of Tool-Ranks promotons, about a year ago. It goes with me to every job, large and small. I keep the tools that I need first on the job, for layout and measuring, plus a basic set of hand tools that I can cover my small jobs with. My bag usually sits outside in the sun all day, and for the year or so that I have had it, it has not faded one bit. This bag has survived being loaded in my truck with all the other assorted tools and material surprisingly well.
This bag holds a surprising amount of tools in an organized manner, I can find my tools without having to empty half of them out on the ground to find that one tool buried in the bottom, this is a big time saver and does keep the job site much neater.
The only thing that I can complain about with this bag, is that it does not have enough larger pockets in its back row. It has one larger pocket on each side, that can hold torpedo level sized tools. The rest of the row has screwdriver sized pockets. I needed a space for my larger Channellocks and had to put the handles in two different screwdriver pockets. If I was to customize this bag I would make one side with large pockets and the other side with screwdriver pockets.
I have heard people complain about the weight of these tool bags, all I can say is that whatever you load with that many tools will be heavy, tools are heavy. This bag carries the weight well, both by its carrying handle or my preferred method, the shoulder strap.
Would I buy another? Yes, although I would consider some of the other sizes as well. The XXL-F is looking very interesting.

I did post some pictures on Tool-Rank, in the Photos section. http://www.tool-rank.com/index.php?option=com_community&view=photos&task=album&albumid=63&userid=109&Itemid=200095
