I have used both tool rolls and tool bags. My choice is a tool bag.

I keep assorted tools in a medium sized (aprox. 3"x10"x3") mollie bag. It is not a special bag for tools so I can change it as my needed tools change. Much smaller than a tool roll. To eliminate noise, I have a couple of straps that compress the bag tightly. The bag is designed so the top can be folded back around the sides making a very large opening which facilitates tool access.

I keep a small (aprox 20" square) bit of cloth in the bag. When needed I can dump the bag on the cloth to provide easier access to the tools. I usually do this only for "long" projects.

The cloth also provides a good "field expedient" workplace to prevent the escape of small parts. I sew a small border pocket along all the edges so parts can not slip off the edge but instead will be trapped in the edge pocket.

I have been using this method in one form or another for over 50 years now. Tool rolls take up much more room and are not adaptable as I discover new (and usually better) tools. With the bag I just abandon the old tool and drop in the new one. With a tool roll, I need to modify the roll. Not always an easy task.

Actually I have 3 tool bags. The largest is a open topped bag with many pockets. Left over from my "messing about with boats" life. It is my daily use "fix everything" bag.

Then there is the smaller one mentioned above. It goes with me when ever I leave home in a vehicle or flying (as checked baggage).

Last I have a small belt sized mollie pouch with just my "essential" tools. A bit heavy, but being a tool using creature it is worth the freight. It consists of; 6" vice grips, 6" channel locks, leatherman (original, small flashlight, 4"wire cutters, 4" long nose pliers, Kobalt mini screw driver with 1/4" hex very small bit drivers in the handle and a selection of 1/4" hex bits in a small rubber holder. It rides on my mollie vest, on my belt or in my carry bag as appropriate, but is never far away.
