I collect all CI, but I mainly collect Wapak. I guess for me, the reasons I love Wapaks are that they are kind of easy to date ( 1903-1926 ), not a lot of variants, every Wapak is unique in that they all have their flaws somewhere on them ( that's what I love ), they were I'm assuming a small outfit compared to Griswold, Wagner, Lodge, ect. They are also lightweight, smooth as glass, cook very well. Finally, I like that they have just enough different logos to make things interesting, and keeps you guessing.
