Underspin reels like the Abumatic 1276 hold up well to heavier fishing conditions. Switching to a taller framed stripper and next ceramic guide on the fly rod will improve it's spinning, underspin, and not hurt it's fly performance at all. Just check the guide height to your rod sack and rod tube interior dimensions to make sure they fit before selecting the stripper guide size. A double foot 16 or under should probably be ok, but check.
