One I thought a Heavy Arrow would fix?

No!! Definitely not!

I would Never use a setup hoping to compensate for a poor shot. I have learned to take shots I know I can make, not weight my arrows or use huge broadheads to compensate. All the variables you mention fall under making a Poor shot. Most times they can avoided, but don't think anything will Bail you out when it happens. That line of thinking will Not fly!!

I've seen poor shots and lost deer from every kind bow, arrow, broadhead combination imaginable. It all comes down to poor shots lead to lost deer regardless of what you are using, but them Duke Boy arrows might work. Could be hard on the mount and the meat though[8D]
