I should have paid better attention to Mustad's changes.
Apparently they have stopped production on 34007 and 34011 hooks and many sellers are now either out or sell limited sizes. I use these extensively for large insect patterns (dragons and hoppers) and small poppers (using the 34011). Eventually I'll have to change to something else, but for now I managed to find some at http://www.tackledirect.com/.
I have also found problems with 37187 bass bug hooks.
