JMO, but I never shoot below 6 grains per lb and never will!
I believe, even though manufacturers warrant for 5 grs per lb it is still too low.
Most bow manufacturers never did want to warrant for under 6 grs per lb.
They do only because they finally gave in to pressure from those first manufacturers who began to warrant for the 5 gr. limit.
My current arrows for my Bowman and Merlin bows are 6.7 to over 7 grs per lb.
You almost never hear of limb problems with heavier arrows like you do with 5 grs. per lb and below.
Anytime I read a post about someone's limb exploding or cracking, I can't help wondering they probably shoot 5 grs or less.
