Yes. Cocoons are the best I've purchased. I've also used the cheap ones offered at local drug stores. They work. Then I got contacts.

I don't target Gar, exclusively. When I fish a local ditch, I will cast to them. Most are laying on the bottom and won't hit unless you drag the fly right in front of their nose. They are a ball until you get them on shore and the wrap themselves up in the leader.
