Okay guys I need alittle advice. I currently am shooting Carbon Express Maxima 250. I am shooting a Bowtech Tribute 28" draw 70#. My arrow weighs 361 gr. total with 100 gr. heads. A tech from Bowtech told me my arrows should weigh between 375-425. So should I use 125 gr. heads, which would put me at 376, or should I opt for Maxima 350? Thanks in advance.
