I need opinions from current users. Which do you find more comfortable.

The Gen 4.4 or the old model had this part leather and part fabric but non articulating shoulder strap.



The current one used in DH and D2 models look like this:

I know the current one is lighter and supposedly more ergonomic.

Any real user experience. Sometimes I gotta go the distance and need something that is comfortable. (I already have the op tech stuff and that is the reference in this comparison)

Please chime in.
