I really can't say. The hook is one of the most important decisions when I try to imitate something I have seen. As a result I use all kinds, Many which are not considered dry fly hooks. I've even tied them on tubes. The brand I've found most reliable is Tempco, but they are some of the most expensive here. Recently the price has gone up 20% (they reduced the number of hooks in a pack from 25 to 20). That has made them prohibitively expensive for me. Now I only use them by customer request or if I pick up a pack that's reduced. Variety is the spice of life after all.
