Hi all, I'm pretty new here, but have been reading for a while, and would like to thank you all in advance for the great advice I've received while reading your posts. My question is this... I shoot a Ten Point Pro-Fusion, and currently use 100 gr heads. I saw some broad heads in, I believe Cabelas, that were very heavy, if I can recall it said they were upwards of 170 grs. Is this common practice in crossbow hunting, to use such a heavy head? Does it compensate for shorter shaft length, etc? Forgive me if this has already been discussed.
