But have you tried the BD Quantum 65, 55 or 45.
I've used it for since the Shadow was discontinued (about 5 years ago) and I fell in love with it. Fantasic load carrying, good features, no features which you'll never use, good size, loads more and it looks great.
Have no knowledge of the 2 your thinking
