Anyone shoot less than 9gpp?

I used to have an 89 pound longbow, I drew the arrow until the broadhead  would touch my finger to insure that I got it all the way back.  I once made myself some arrows for a 70 pound bow and was surprised to find that with 125 grain points, they flew better than the heavier spined arrows that I  had for the big bow.  I stopped off at the Footed Shaft one day, talking to Lamont about my bow.  I had it with me and those arrows, I was looking for some broadheads for them.  I was a bit shocked to find that they only weighed 540 grains.  That would also explain why my left eye ball would try to jump out of the socket when ever I shot those arrows.  It is a catch 22 that I have run into with some other heavy Hill style bows, when the bow weight gets to a point, the spine required goes down in the spine versus bow weight ratio.
