The latest Fly Fisherman magazine has a fly pattern called The Cat. It's tied using spun deer hair for the head. I don't mind spinning deer hair, but silicone floatant is not readily available here and I really don't like using it. I used a piece of closed cell foam for the head on my version. The zonker tail really gives it great action. I put one together and went to my local pond to make sure it would float right. It did and got a lot of action, and even bream had a go at it.
