When working with beads you may need to flatten the barb as the bead will not go over it. Also depending on the diameter of the hook you may need to put on an under warp to keep the from being too sloppy and on a thick hook you will not. Like DB4D said, those are for heavy flies. The longer the hook shank the better the chances the fish will get off. I always use the shortest shank possible even if it meant changing the pattern. If you need a hook for minnow type streamers I would strongly recommend you learn to tie Tube Flies as this is what they are meant to do. With the tube fly you can have the long feathers for the body and a short hook. When the fish takes the fly the hook stays in the fish and the fly goes up the leader. You would have the best of both worlds.
