I like the C&F design too. There was an article last year in a fly
fishing mag. Sorry but I don't remember which one. They discussed
about 10 or so different boxes. They liked the C&F too. You can get
extra pads for them. I plan on getting some extra pads for specific
types of fishing, say bass/blue gill fishing. They pop in and out
easily. I have two boxes and plan to get one more.

The compartment boxes mentioned in this thread DO hold a lot of flies
and I tried them but it seems the fly that I wanted was always on the
bottom of the bunch.
