Just realized that this thread is over 2 years old, but did not catch whether OP ever bought a bag------might not need any more advice or input at this stage?
FWIW, I've really enjoyed my 5.11 RUSH 12 for the past several years as a compact yet versatile and highly organizable everything bag. Just returned from almost two weeks overseas using it to store & carry a wide range of stuff all over. I own it in black, so the MOLLE webbing is not that noticeable, and I add an innocuous patch and pens to the exterior to render it fairly non-tactical in appearance. Tons of pockets/compartments. Very rugged. Still looks new after about 5 years of moderate use.
Again, maybe it's a moot point at this stage.
