Niclas, I have the one they call the Large Waterproof Fly Box. It has an o-ring seal and room for large and small flies (I use it for streamers & bucktails). I can't imagine anyone not liking these boxes. The foam doesn' get damaged like other foam boxes (because of the slits), and I don't recall a fly ever coming loose from it's slit. This particular box is heavier than most of their others, as the case is a different material. I had originally purchased their 'Streamer Fly Box', which was extremely light, but ironically wasn't really large enough, IMO, for a streamer box.
If you're selecting it for nymphs & the like, I think you'll appreciate the extra capacity the leaf gives. I have a slotted (not slits) Wheatley with a leaf and it is a great nymph box. I'd highly recommend the C&F boxes. CD
