Before I messed up both my rotator cuffs, I went the full gamut over the years from recurve to an old Browning Explorer 4-wheeler, to a MacPherson and a Jennings single cam. As the bows got faster and the letoff greater, I found that they got harder and harder to make accurate shots from a tree stand. Unless my form was perfect and I fired by arching my back properly, the shots would stray from POA. Also the bows got louder as the speed increased. I finally decided that it was counterproductive to continue in the "arms race" and stayed with the Jennings single cam rather than buying a faster Mathews every year.
For hunting, speed isn't always the best way to go.
