I have the 2u roadrunner bag (2nd time I own one) and I had the 4u. It is a great case buck sucker was way to deep for my liking. RR really needs to add a 3u to the line upI like the RoadRunner 4u rolling porter bag. Its got a great padded pocket on the front designed for a laptop(has cable pass throughs to the rack below) but I always used it for a space to store cables. You could always buy a 1u rack drawer for that if all you have is the Axe and Martrix. Its a sturdy bag and very mobile!

I used to keep stiff back there too. Right now I have a power surge and g50 velco'd to to the pouch on top of my 2u. I use a right angle power plug and feed it up through rack and use a right angle 1/4 inch and feed it through rack for g50Yeah, its deep, but I liked that cause it allowed me to put my G50 receiver in the back behind the Axe. I had a Gator Rolling rack, but it was too shallow for my liking. The Axe came right to the edge of the back and I would have to unplug all my cables, power included, in order to get the bag to close. I just wanted something that would allow me to leave everything plugged in to the back of the Axe and give me room to mount my G50 inside. I had pigtails coming out of the Axe for my FOH sends(XLR's) so all I had to do was drop the back and pull out my PC power cable and the 2 XLR pigtails and I was ready to roll. Worked for my needs until I decided to go with a rolling ATA rack.....
