The principle caveat here is the bend of the hook & varieties of different hook brands . Barb or crimp the barb down to allow the bead to be slid onto the hook. The next potential obstacle is the bend. A Sproat hook has a uniform bend to the hook, which best facilitates the bead sliding all the way up to the eye of the hook. A Limerick hook is not suitable for a beads. Some Scud-Pupa hooks require a little assist to squeeze the bead up along the shank. Also, notice beads you buy in fly shops have two sized holes. The smaller hole goes over the hook point first. If you put the large hole first, once the bead reaches the eye of the hook it will extend too far and partially cover the eye, so reverse it. Bead shop beads are quite pretty, but the holes are a uniform size. If you are exploring a bead shop, first they are not weighted as a rule (plastic/glass). Also, take your hooks along and ask if you can experiment in sliding beads over the point and, the hard part, around the bend of the hook. Better to ask then buy hundreds of useless beads. When tying patterns, you will need to secure the bead forward with thread wraps and materials to stop the bead from sliding back over the fly even a little bit. If you notice your thread mysteriously breaks at the rear of the bead; some cheap beads are abrasive at the edges of  the larger hole and as you wrap the thread at that point, the thread is cut by the irregular edged bead…doesn’t happen often, but should it…that is why.

Odd, I can remember about 20 years ago when bead head patterns came about. The adornment of a bead was viewed by older tiers, in my circle, as sacrilegious. I recall a shop owner swearing off beads and not wanting to carry them in his shop. Of course, he was a competent business man, so the beads were brought in by demand. Eventually, the pattern bins contained bead head patterns. It is good for beginners to know that many patterns were not weighted with a bead or even lead wraps on the shank. The weight or sink rate of the fly line used was the determining factor in sinking an unweighted fly. It is good strategy to always tie weighted and unweighted nymph patterns. Use a different color thread for the thread head to differentiate weights of flies in the box. An unweighted nymph in 1-3 feet of water with a floating or intermediate line is much more efficient and tactically sound than the kur-plop of a bead head, bead chained eyes, shank wrapped fly, especially if a minimal or slow decent is required. Presentation, presentation, presentation….do you want the fly tracking mostly horizontal? Or, jigging in an undulating up and down and forward combination?
