Purchased a dozen Spartans 250's and I'm working on building them. I am looking a the 30 and 75 grain weight inserts from black eagle and the 50 grain halfouts from kudu. What are the pros and cons of either setup? My total arrow weight with each setup is 467 and 512 with the inserts and 482 with the kudu halfouts. My set up is a hoyt pro defiant set at 80lbs and a 27.5" draw.
