I am upgrading from my old Velbon tripod to something a bit more sturdy. Thinking of the Manfrotto MagFiber 055MF3 combined with a Markins Q-Ball M10 at the moment (but would really appreciate pointers to reviews, they are quite hard to find on tripods). Now... If I buy the combination above, am I then all set? Or do I need any other stuff in between? I read of leveling plates and "QR", but I don't know what that means! Do I need a QR or a leveling plate?
