Oh I see what your saying as far as the weight. My bad. I havent been around the new arrows and didnt recognize the numbers so I wasnt aware he had a heavy arrow/light broadhead.

Yes this " can" effect arrow flight and tuning your bow will definetly help. Although I wouldnt paper tune it, I would do what we called " group tuning" it. If you know what your doing anyone can manipulate the paper but group tuning is by far better in my experience.
