That is a #10, but have been thinking of tying some on a Wide Gape fly hook on a #12. Heck you wouldn't believe how small of a bream I have caught on a #8 curved hook that is not short either, on the Bream Killer Fly. I wouldn't have though one that small could eat it, be he did, LOL!

They call that a Popper Dropper when you drop a Bream Killer off behind a popper bug. That will work for sure!
