Ridge,
Glad to see you practice with broadheads. Some guys just assume they will fly the same, or don't want to bother trying to fix it if they don't.

I don't know mechanical heads because I shoot fixed blades, with fingers and feathersno less. The trick really is in spine selection and tuning. I used to get good groups with field points, and it even looked good going through paper, but a bare shaft would plane several inches at 30 yards, and miss a stack of hay bales at 40. Broadheads would be very erratic and inconsistent. Making adjustments and changing point weight helped somewhat, but I finally had to get weaker arrows. This was the key. I'm now within a few inches at 40 yards, and I'm just a tweak away from perfection. Can't wait to get them right on, and have 100% confidence on opening day. It's getting late, but you're better off getting things flying right with the points you already have.

Good luck.
