If you can't narrow the problems down to one arrow, one BH or one insert...AND you can shoot the arrows with consistency and precision for 20 shots on some days...then the answer to your question is YES, you must lose it and alter form.

If not, explain to me how a broadhead can perform well with 20 shots on one day and then produce errant shots the very next day?? The broadhead/arrow/insert combination didn't change, your bow set-up remained constant, nobody played with your target...

I guess that only leaves human error...

And yes, broadheads will show form error much moreso than fieldpoints. Changing your anchor point might make a fieldpoint miss the mark by 4"---that same miss might equal a foot with a broadhead.

And I'm also curious, what were your old heads, fixed or mechanical??

And a final question---if you were so unhappy with these BHs target shooting before the season started, then why did they accompany you to the woods for hunting purposes?

In a nutshell, are you positive you don't have any form flaws, and why would you take a chance with these heads if they performed so poorly prior to the season???
