I have the 200 and love it. I've had no issues with pot calls falling out of the pockets. I am considering the 300 but then I can't think of a reason why. Usually after some long stents of hunting I'm trying to take stuff out of my vest to lighten it up so I don't think I'd need any extra storage. If you don't have the 200 it can't hurt to go with the 300 and have the option of extra storage though.
