Does anyone know if you will have all the couriers stashes all together or if you have to pick one at the start of the game or something like that. Thanks. Discuss

I don't know, but I imagine you can pick which ones you might want. Just throwing them all at you would make the start of the game so much easier, especially since most of those weapons don't have skill requirements (so, someone who doesn't have explosives can still use the Merc Grenade Launcher, for example).
