Lye-ka, better than lay-ka.
although I hear that the laykas did pretty well last season.
I say Nyekon, not Neekown.
Hasselblad is fun to say because you can use a different pronunciation each time you say it. I like to mix it up and say "Hazzablad" sometimes, "Hass-il-blad" others, "Hassablad" and "Hasselblawd" also work.
Though mostly I call it a "Hooselhassel" because one time I walked into Calumet on 22nd st in NYC and that's what the funny guy behind the counter called it.
