Larry, your comment on the shooting qualities of the bow are right on. In fact, that is why PSE bought the company in the late 1980s (they were particularly enamored with the forgiving nature of the bow, especially the grip). They wanted to adapt the riser for a compound bow, but it was not strong enough. So, they had to make more extensive changes (including to the grip) and finally brought out their Carroll compound model in 1989 (as I recall).
