Mossy:

What size of shaft are you shooting? Do not just blame the heads and believe that changing heads will be a quick fix.

In addition, that " ...slight wiggle" you mentioned is an indicator something is going on that needs corrected and should not be lived with. That slight wiggle can become something greater if the flight problem is compounded by another problem.

You could have a shaft spine problem and/or a bad vane contact problem. Incorrect nock height can also cause erratic arrow flight if the nock end is striking the shelf, or in your case, the rim of your " WB." Bad torquing should also be considered. You might try shooting off a standard rest to see all of some of the flight irregularity disappears and your accuracy and grouping improves.

PS: Dump the vanes, their shot! Install new vanes on your shafts…5" .
