ok thats what i thought it means i am drawing about 30 inches. i don't feel it stacking, however i am not sure i would notice. it also explains why the bow feels so heavy, to me. I am going to try to shoot it with my natural draw( about 30"). i might have to build a bigger bow! the arrows i got are 8.4 gpi >> X 30 inchs + 125 point = 377 grains. Or about 7.5 gpp thats legal to hunt with here (lower limit is 6 gpp) seems a little light to me to stick pappa bear with. late deer season is nov 19-21 sure would be nice to be shooting my new bow! and momma and pappa bear are regulars on the clearing i intend to hunt.
