Current bag is a 42" UTG

It has a single shoulder sling that carries terribly. When all the mag holders are fully loaded, the bag is bulky and akward. The bag will not close with a 30rd Pmag in the well due to the aimpoint...no bueno. The bag does not have internal velcro to hold the weapon in place during transport.
I need a bag that is not super bulky with huge saddlebags because it will ride in the trunk along with a billion other things that cops feel they need in their vehicles (fire extinguisher, crime scene box, tools, tire, camera, AED, first aid kid, paperwork...etc). However, I need for it to carry the torque wrench to change barrels (more so I don't lose it), a small cleaning kit, and some loaded mags (I also have a bail out/active shooter bag with mags/trauma kits etc). I want something high quality so cost is not a primary consideration. I am looking to switch to a rectangular "discreet" type case, not to be secretive, but because I feel like it fits a patrol rifle, 30rd mag, and raised optic better. Also easier to use what pockets the bag does have. I'm looking for a 36" case as I feel the 42"s are too long and bulky.
Here are some that are in the running:

The Condor brand cases look great, but I think all that stuff hanging off the sides will clutter up my trunk. If you guys have a chance, please click through the links as there are additional photos of each that I did not want to clutter the thread with. Thanks in advace.
Also - if someone is crafty enough to make a case, I'd be willing to consider having a custom case made. I know TT (tactical tailor) can but he is busy with orders for alot of SF guys playing in A-stan, so an off the rack case is probably my best bet.
