Hi all- I figure there are enough more qualified experts here to lend me a hand. I shoot an old Mathews Z7 Extreme and it serves me well so I haven’t felt the need to upgrade yet. It’s set at 65lbs with a 27” draw and my current arrows are cut at 28.25”. I’m hunting elk using Iron Will S100’s and I’m thinking of Easton Axis 300’s and 50 or 75 grain inserts with 25 gr collars, but I’m looking for any recommendations or feedback to this for arrow length, spine, and weight to use for inserts?
