Me too! LOL It's funny, some years ago we hated carbon arrows cause they typically made an arrow too light for our liking. Then a few manufactures started making arrows in the 8-12gpi range...Now I want some of those light but stiff shafts. It's not too hard to get high FOC's in shafts weighing 700+ grains but those are getting excessive for bows in the 40-50# range. Some of the target shafts might work but tend to be expensive.
I had some 35-55 Super Carbon Hunters laying around, I think Beman made them. They are 5/16" diameter and static spine 60# and are about 7gpi. With an 8" internal foot, 29" shaft length, 100gr brass insert, 4" fletch, aluminum adapter, with a 125gr head, they have an FOC of 27% and weigh 500 grains! A fellow might be able to find some of these on **** or stuck in the corner of some archery shops....O.L.
