Hi,

Well, I'm no expert, and I've not used CDC myself. Still, a size 16 light wire hook should be ok I would think so I doubt that is the problem.

A bushy body helps trap air bubbles, which aids floatation, so it could be the floss body as it would produce a slimmer profile to cut through the surface tension, and it would not trap any air, and so would add less to the floatation.

Provided you're using an amount of CDC similar to that in the pattern instructions, then I would guess the floss body is the problem for the above reason. Tie up one with the punch yarn body, and see if that works. If you don't have punch yarn, then dub the body with hare's mask, or wool, or any other "bushy" dubbing material.
