First time here.
I picked up the 300 and really like it. Don't know about durability yet. I'm 6'3"/300 pounds and at first, thought it was too small for my frame. Once I adjusted it and took it for a stroll, found that it fit great. I like how I don't feel like an overstuffed turtle wearing it.
It holds all of the stuff that my previous vests had in them. 2 pots outside, 1 in the interior pocket (has a pocket inside for that), box call, mouth call, shears, compass, hydration bladder, tp, etc... On top of the exterior shell holders, it has interior shell holders on the right exterior pocket above the waterproof cell pocket.
I used the decoy stringer to attach a decoy bag to (didn't like the thought of decoys being out and possibly falling off walking)----the thing has elastic cord and I attach it to the collar. This allows me to easily reach around and move it to the front to access the bag and deploy.
