I have several BoreTech rods, and will not buy more.....They are in the corner of my loading room. Coating material comes off, and customer service is lacking. They do have a nice handle.
I'm using Dewey, and some custom rods, now.
Don't know much about the carbon fiber rods, but heard they flex a lot.
Just make sure you are using a good bore guide of the correct size, and watch that rod exiting the muzzle---that's when most damage occurs.
