Pro Hookguides are easy to use: Just plug the larger diameter tapered end to the port or back-end of any Pro Microtube or Pro Nanotube. Presto! You have a flexible, durable hookguide for all ring/straight eye, short shanked hooks that are popular today when fishing tube style flies. If you like to fish tube flies with a non-slip loop knot jammed into the tube, don't worry, Pro Hookguides are still a great compliment to that style of rigging. Tippet knot will jam just inside the tube in this case allowing the Hookguide to stiffen a good portion of the non-slip loop for less or nearly zero chance of "fouling" the fly.
