I've own both the Dewey and Tipton .17/20 rods. You must be very careful with both of these small diameter rods, especially if you try to force a tight patch/brush. That is how I bowed my Dewey rod and I cannot get it completely straight again. The coating will also be scraped off if comes in contact with the chamber/bore if it bends. My Tipton fiber rod has broken a couple of times at the base of the threaded metal tip. But at least with the fiber rod you can repair it. I carefully sand off some outside diameter at the tip of the rod and fill a female threaded .17/20 cal Hoppe's Elite jag with epoxy. Then threaded it back on the fiber rod. Now it is a dedicated rod for my .17 and .204. The Wipe-Out bore cleaner works well for me without having to use a brush.
