which filter wheel for mounted/threaded Baader 2-inch filters

[VisualUniverse]

I am about to order an Atik 383L and an Atik 5-position filter wheel. Seems Atik has several models. Which one would I order to use with my Baader 2-inch mounted/threaded filters?

Thanks,

I'm guessing that you already have 2"mounted filters, so you would get the EFW2 with a 5x2" mounted disk.
