What did people do before mechanicals?
We tuned our bows to shoot broadheads straight and accurate. When it came time to shoot field points, a lot of us had an extra set of sights for our dovetail mounts and we simply switched sight bars (very few sights on the market any more with dovetail mounts). Most just resighted the bow.
If your broadhead arrows are flying straight with no wobble, then move the sights to compensate and go hunting.
