Coley,
Drop me a line if you are in the area and we'll hit the beach.
I think the head is too big. Several of the cutts popped it in the air like a seal playing with a ball at the aquarium. I agree on the gap as well.
Regardless of whether I use a standard hook or a stinger, I seem to miss a lot of topwater fish.
I got some smaller foam today so I'll see how that works. It will ride lower in the water so hopefully that will increase the hook- up.
Here is the smaller foam versus the bigger head.


I've been playing around a bit with the clear Fish Skull Fish Masks. So far I really like them.


Sam,
Sparse is good to a point. Just don't ding the beach as sparse can become a bare hook.
