There are no mass-produced commercial rods that can deliver optimum performance. The best route is to have a rod made from the finest of rare materials that is custom-fitted to your barrel. If a person is not willing to spend the necessary money to go first-class, the next best thing is to buy a commercial rod and discard both the handle and the rod. The handles on commerical rods are either wood, which will warp, or some inferior composite that lacks the necessary stiffness to do the job properly and should be replaced with one that is hand-laid up to the exact contours of your hand. As for the replacement rod, the debate over material is never-ending. A person just has to make a choice and live with the knowledge that no matter what he chose, he is wrong.
