So my 320 Bianca arrived today. I tried to put the adapter in but it was pretty tight and wouldn't seat, so I just went without anything and packed up a bowl of Maltese Falcon. I really enjoyed smoking this pipe. It's beautiful and feels really good in the hand. The only problem I had was when I needed to relight close to the end of the bowl. I ended up having to put the lighter pretty close to the bowl because of how deep it is. I have a Zippo with the pipe insert, but it isn't the directed flame type. I've been wanting to get the z pipe insert anyway, so we'll see how that does. Thanks for all the feedback gents.
