About deminshing returns. I liked heavy bows. Jack Howard argued with me about his bow if I ordered a heavy one. I figured, okay, so every bow was different. At one point my wife was shooting a 45# Big 5 and I was shooting a 90 pound Big 5. Our draw lengths are the same. The problem i had with cedar arrow is that if I went with a 90 pound shaft with a 160 head, they were too stiff and mine weighed only a bit over 600 grains. I made some 80# Acme cedars 27" bop just like the others and they weighed only 570 grains, but they flew straighter. That is not a very good ratio, but they flew through deer easy enough. My wife's bow had no problems shooting 50# arrows 27" bop that weighed bit over 10 gpp. One day we were shooting for distance and I had shot some of my old target arrows with 4" four fletch out of my wife's bow. To my surprise, they flew perfect and they flew a lot further than my arrows. I weighed them, 6.5 gpp, that was almost identical to my gpp ratio. I would never hunt with a 260 grain arrow, but somewhere somehow, the static hysteresis difference showed up comparing those two. I fixed my light arrow problem by going to fiberglass arrows with a hardwood dowel glued in the lead third of the arrow. The other observation was that the heavy arrows did not lose as much speed as i expected from the heavy bows and the same arrows would fly out of all of my over 75# bows. Some bows pay a higher penalty with heavy arrows than others. I think that ASLs, they are slower to begin with, but they do not lose as much cast with heavier arrows due to the weight of the limb versus stored energy of the less efficient design.
