A:
The Ribbit hooks sold here in size 4/0 fit the lure perfectly. I'm sure the 5/0 would fit, but the hooks may be closer to the legs and impede some action. I only need the 4/0 for where I fish.
Unweighted will allow you to run it on top easier. Weighted if you want it to dive quick when you give it slack. It depends on how you want to fish it.
