I shoot aluminum arrows. Most of my bows are aroun
45# @ 28" and I draw 27". My first questions would be what is your actual draw length and what is the weight of the broad head you want to hunt deer with? The spine of the arrow will be affected by the length of the arrow and the weight of the point. Depending on the bow, I normally shoot 28" to 28.5" bop length arrows, with a 175 gr pt., with either 1916's or 2016's. If you are drawing an actual 28", I would think, 1916's would be to light of spine even with a 125 gr pt.
