RE: Kenetic energy
Doug, it was a very unforgiving bow. I shot it with fingers too. If I wasn' t spot on with my form, it was hell getting it to group. I had to shoot it at an indoor tournament one day because my indoor bow was down. The club had a fairly new target wall of cardboard and I was shooting clear thru it and had to drop out. I once shot a robin hood with it at 30 yards, and drove the 2512 shaft almost all the way thru the other one. Sucker hit hard. It was a dual hatchet cam bow w/ 65 percent let off. Very small valley with a rock hard wall.
Back in those days, speed was the most important thing to manufacturers. I think they got away from that a little bit to concentrate on both speed and forgiveness.
