What is the difference between the Helleberg and the Helleberg II? I notice that both R&S and Schilke make them. I am very familiar with the Conn Helleberg and Helleberg 7B. I also have a Shilke Helleberg, which I notice the rim is not as flat and the rim diameter is a tiny bit smaller than the Conn.
