I just got a ripping deal on 15 new 2-04 920 acc shafts and 2dz points. $40 for the whole works!!!! My question the points are only 50 gr. It seems awful light. I see I can buy 80 or 100 gr points. Wouldn't my FOC be way off with the light points? I Always have shot heavier points if I could. What you think?
