RE: What gives with my arrow flight?
The draw force curve of the Iron Mace is close to the BT Pro 40 Dually draw force curve.
That with your 29" draw and 29.75" arrow your current arrows are under spined you really should be shooting the 340's or ACC 3-60's with a 100gr head.
Adding a wrap to the back of the arrow is not going to do a thing for your current arrows.
