I own a Sage RPL - an older model for sure. I love how it fishes, I have broken the rod four times and always had a pleasant experience with warranty from Sage. I have since received a St. Croix Imperial 9ft 5wt rod and now fish with it exclusively as I love the action and the rod in general. I can't compare it to the Sage rod you mentioned but I know the St. Croix does everything I've ever asked for from a utility rod: delicate dries, heavy, multi-fly nymph rigs and streamers. This rod gets it done. Good luck on you selection.
