At the present time I am shooting beman ICS 340 arrows, which are 9.3 gr.with a length of 29 inchs. And have Muzzy 100 gr. broadheads on them. I am shooting 62 lbs on my bow. I was wondering if I was to shoot beman ICS 400which are 8.4 gr. atthe same length but used Muzzy 125 gr. broadheads would I be losing or gaining anything. I guess what I am asking is it better to use a heavier arrow with a lighter broadhead or a lighter arrow with a heavier broadhead. Or does it even matter. Thanks
