Can't have it both ways, Sitka. A turned eye causes a nymph to ride hook up, but it helps a dry to ride hook down? I think the effect of both is minimal if it's there at all. But a turned eye DOES change the angle of pull from the line. Instead of pulling straight down the hook shank, you are applying a small bit of leverage.
But it's all pretty picky. Fish don't care. They can reject anything I throw.
