Broad heads shooting way different than field tips???

Another thought if you've got a friend with a new iPhone. The camera has a slow motion video feature that is pretty good at slowing the arrow down. Great tool for evaluating form and arrow flight.

As a long time wood arrow guy, I suggest paper tuning before you chance bareshafting.  Paper will tell you the same things without the chance of breaking your arrows, plus you don't have to cut off the fletch.  Paul Jalon has some good instructions on his Elite Arrows site.

Arrows well tuned with field points shoot broadheads very well for me.
