I have always spin tested my arrows and get excellent results when I do. I know what spin testing is and have the spin tester, which is showing the wobble. On my other arrows, aluminum insert. I would heat the insert and would adjust as necessary to get no woble and would always fly tru like a dart after that.Normally a couple turns to even theglue on the insert would get rid of the wobble but other timesi would have tocenter it.

Is there a way to spin test and fine tune these broadheads with this type of insert??
