I just got a second hand 60# supermag 48 a few days ago. From the looks of it, it was made in the 90's or early 2000's. Its really a neat little bow, although the extremely high grip takes some getting used to. On the plus side, grips like that tend to add an inch or more to my draw length when compared to the low to medium grips on my other bows. I can say with certainty that the ulta short amo makes any error in form really noticable; Its not a very forgiving design. I am very happy with the bow in general. Its a perfect bow to accompany me in the thickest dark timber next September.
