That is the new tip. They read complaints and have been correcting them. People complained that the old tip was loose and wobbly. You should also have a better chimney o-ring than most people. It is set deeper into the top cap, so it's not as easy to lose. I hear the newest versions even have adjustable center pins, but haven't confirmed that yet.
That's right, the old tip was very loose and the hole was too small for many people who wanted a more airy draw. So they modified the tip with two o-rings and enlarged the hole. I removed the bottom o-ring and it's plenty stable with just one ring. The o-ring in the top cap is set deeper and doesn't come out now. But when you unscrew the top cap, you will unscrew the chimney also unless you make sure the chimney and base are really tightly screwed on. Unfortunately, the new version still has a one-piece center pin that appears to be a screw you can turn to adjust. But if you turn the center pin, you will end up unscrewing the positive post on the deck. It's a fixed center pin; don't try to unscrew it, especially if you have a coil hooked up. I was expecting an adjustable center pin in version 2 and was disappointed such a key feature was left out.
